A tiny home such as the house on the picture is affordable by all hard working people around the world.
A home such as the millions of luxury homes in many European and US households, paid entirely or mostly by mortgages and loans however may risk foreclosure at any time.
The difference between being modest and humble or being eccentric and luxurious is that the modest and humble people will survive while all the luxury may implode like soap bubbles and leave millions of families homeless.
The size of a home has nothing at all to do with the potential of happiness of its habitants. Families living in small homes however have a far greater chance to BE happy than rich ones, because simple houses can be OWNED and thus simple houses never cause problems or homelessness. Housing paid by mortgages however may cause constant fear of foreclosure and homelessness to all its habitants.
Decision making facts when purchasing or building a home:
If all world, every single family on this entire planet would own a house simple and tiny like the one shown on this picture. A home big enough for a truly loving family in peace with each other. There would be no problem for the planet at all to sustain any number of such houses for the entire global population.
If however all world, every single family, would own a large luxury size home such as the typical US houses - with hundreds of square meters, with 4-6 or more rooms, aircon, and much more ..... The the entire planet would collapse from the excess of energy consumption, waste production and resources used to build and maintain such huge homes by the entire global population.
Hence small houses can be supported by the planet. large houses would / will kill the entire planet. Once the ongoing killing of this planet has reached a critical point, the entire planet may collapse / self destroy within seconds or hours with no remorse and with no chance of being rescued by humans. It is the greed, stinginess and total lack of wisdom that will eventually destroy the planet at some point to a degree to make the planet impossible to be populated for a very long time.
What will happen to mankind then ? They all die and many may wait in astral worlds millions of years until another space to continue spiritual learning has been made ready for a repetition of the failed lessons. Those however who have learned to live in a modest nature friendly way also have proven to be able to live at home for the remainder of their eternal life - thus they may return home to God. All others first have to prove what needs to be learned and mastered NOW and HERE on earth. Modesty, humbleness, true love - to share and to help each other. To treat all as equal beings with equal rights.
