You can't meet all your needs/desires at once, even if you spend all your salary
There is a thing called contentment, which you haven't discovered yet.
Contentment is something that's very good and it's a virtue everyone should have but being contented doesn't mean satisfaction.
Humans should be contented with what they have but it doesn't mean they should be satisfied because human wants are insatiable as they are tied to growth (in all ramifications of life) so we keep striving to get more.
First I would say "human needs are insatiable."
Not true. Some people's, or a lot of people's if you like, but not everyone's. I insist on the previous comment. The rest of what you say, since it is based on a premise that I consider false, I do not agree with it.
As much as you're a human and alive you are bond to have one need or the other. Our needs keep piling after we solve one another will submerge.
In fact for the very reason that humans are faced with unlimited wants but with scarce means to meet those wants it then entails that no man can be satisfied in life he will always be in need for something to keep life going whether we agree or not.
