There s an illusion sold by medias for decades, that in this day and age you can do and have everything. Fact is, you cant. You still need money, and to get money, to work, or be born of someone who has money.
Now there are many strategies of survival, I'm always surprised by how people manage to survive, whatever their incomes, how they cooperate with each others.
It doesnt take brains, a high IQ or money to survive, many people survive using their looks for example, to get the money or the person who has the money.
Many ugly, handicapped people survive simply because other people take "care" of them and as a result get a job and salary.
The point of life for any life form is to adapt to survive, whatever the strategy of survival.
Nowadays you can get a "home" for 5000 bucks:
