I completely agree with the OP. Let's be honest - you don't NEED a 100 k car right after graduation, even if you're earning a 100 k a year(I've seen this happen).
What he's trying to say is that there's a huge difference between NEED and WANT that people often mis-perceive.
If you only buy shit you NEED, you can save up, then quit your job and do things that you WANT to do, without having to worry about job security, next paycheck et cetera.
But people feel entitled. They DESERVE the car, they NEED the house. The economy would die if everyone was frugal lol
