A simple happy peaceful life doesn't mean living under insufficiency of lacking the basic needs for life maintenance.
A simple clean and tidy living and resting space or shelter as well as enough basic clothing that protect the physical body from the impact of harsh weather, injuries, insects and wild animals in a healthy natural non-polluted surrounding environment, clean air, adequate simple nutritious food consumption that generates enough energy and nutrition for maintaining the basic function of the physical body and the thinking faculty, clean safe drinking water, basic hygiene and sanitation, certain indoor or outdoor physical and mental activities that don't require any additional equipment or gadget, basic living skills, basic correct understanding or universal conscience with basic common sense, openness, self-control, self-reliance, self-effort, self-inquiry, self-realization, contentment, and certain degrees of mental and emotional independence, are all the basic needs for maintaining a wholesome selfless impermanent life existence of the selfless physical body and the selfless thinking faculty.
There are boundless different kinds of unnecessary commercial ideas, products and activities, food productions, dining options, entertainments, fashions, accessories, gadgets, lifestyles, beliefs, values, practices, physical and mental leisure activities that require certain space, equipment or gadget, varieties of furniture, luxury accommodations, home decorations, pets decorations, toys, commercialized sports activities related commercial products, theme parks related commercial products, tourism related commercial products, celebration days, cultural, spiritual and religious events with their respective rituals or objects for different occasions, health and fitness products, beauty cosmetics products, skin care/body care/facial care/hair care products, spiritual healing related products, health food products, health care products, slimming products, anti-aging products, luxurious pleasurable material and sensual enjoyment of the senses for the body and mind, tourism holiday activities, and etc, where all these ideas, products and activities beyond basic needs for life maintenance are deriving from the intention of empowering wealth generation and accumulation through business investments, property investments, productions, tourism, commercialism and capitalism, under the creativity of the creative minds utilizing the many different technologies and higher technologies designing for catering the 'inspired' and 'empowered' desires and ambitions beyond basic needs for life maintenance of the ever restless discontented ambitious passionate minds under the influence of ignorance, egoism, impurities and restlessness.
The existence of all these unnecessary ideas, products and activities are exploiting the nature and natural resources to the maximum to the point of destruction, while generating lots of unnecessary inevitable rubbish or pollution into the world, and give rise to so much exploitation and corruption that lead to many unnecessary damages and suffering in the world under such greedy ambitious inspirational aspirations and desires of the restless passionate egoistic minds functioning under the influence of ignorance and egoism.
The buddhas and gurus foreseen all kinds of alarming damaging effects in the world deriving from such ignorance, egoism, restlessness, discontentment, dissatisfaction, greed, desires, aspirations, ambitions, success, wealth, status, indulgence, possessiveness and pride, that give rise to so much unnecessary damages to the natural environment, unrest, separateness, discrimination, selfishness, exploitation, corruption, unequal basic needs availability and distribution, unbalanced between abundance and insufficiency, desperation, suffering, hunger, violence and war in the world, and hence, the existence of the basic and yet essential teachings and advice of living a life of simplicity and contentment, dispassion and renunciation.
None need more than sufficient basic needs for life maintenance to be living a simple happy peaceful life in this world.
None need the additional ongoing stimulation of sights, sounds, smells, tastes, sensations, imaginations, visualizations, feelings, and etc, to be pleasing the ever discontented boundless passionate desires, to live a healthy happy life, physically, mentally and emotionally.
There will be minds that disagree with this and don't like to hear this, while thinking and believing that "There's nothing wrong or damaging to be enjoying whatever that is available to us, as long as it's not hurting oneself. Life is too dull and boring without some pleasurable entertainments and enjoyments. The global and local economy depends solely on the boundless desires and aspirations of consumerism inspired and empowered by all these business capital investments, property investments, productions, tourism, commercialism and capitalism, or else, the economy will collapse, there will be no jobs, and everyone will be suffering. But, at least those who have the opportunity and motivation and are capable of making a success out of all these to be generating and accumulating wealth won't be suffering so much. Life still goes on for those who achieved such success and wealth regardless of many others who are being exploited and living in poverty because they don't have the credibility or motivation to achieve success to get out of such desperate situation that exists under exploitation by those who are smart and credible, and those who are smart and successful deserved all kinds of abundance, enjoyments and comforts because it's their own ability, effort and aspiration. There's nothing wrong with smart people who work smart accumulating wealth and enjoying life to the maximum by exploiting the nature and the non-smart people who have to work hard and still not making enough for living. Be smart. Be inspired, and be empowered to be smart and achieve limitless success and wealth."
That's right. Keep inquiring towards what's wrong with this thinking or understanding, for the minds that think and believe that there's nothing bad or damaging with a little bit of extra desires, ambitions, success and enjoyments in life. Unfortunately, very few minds would see what is the 'problem' with this 'system' of a new modern society of 'empowerment towards achieving success and wealth and pleasurable enjoyment' as well as no limit of 'higher success, higher wealth and higher pleasurable enjoyment'.
That's why by being inspired and empowered to be having higher education, higher intelligence, motivation, ambition and the accumulation of knowledge, achievement, success and wealth, doesn't guarantee that the mind will have correct understanding, or is free from the influence of ignorance, egoism, impurities and restlessness.
It's the freedom of all and everyone for their understanding and desire and don't desire, as well as dealing with the consequences of the understanding and the desire and don't desire.
When the climate eventually collapsed, followed by the food production collapsed, where there's very little livable condition left on earth, when hunger, desperation, violence and wars are everywhere, then we will see if the minds still think and believe that they and their next generations won't be affected by the consequences of their 'nothing wrong' greedy boundless desires and aspirations.
Inquire towards the truth of everything.
