Simplicity/Minimalism only For Rich?

I just read this post on mnlist about the thought that minimalism is only for the rich.

I am with the blogger on this one: minimalism is for all economic classes!

I see so many people living in the projects, going from check to check that have waay more than I ever thought of doing.. some people I know spend more on their car rims than I spent on my whole house!

Minimalism would perhaps help the poor even more than the affluent by allowing them to stop worrying about stuff. It would definitely reduce some expenses for them!
