I graduated from college in May 2014 and I'm making 62k right now. No kids, no car payment and I live with a roommate.
I have a ton of disposable income and it feels pretty awesome. Even after socking away close to 40% of my income I still have flexibility in what I want to do with my money. It's really nice.
It's all due to not inflating my lifestyle after college.
One of my coworkers was hired at the exact same time. She lives downtown and bought a mercedes, now she's barely making it. What's the point of driving your mercedes to the nosebleeds at concert? I'd rather drive my beater to the front row.
My roommate makes 75k and before he lived with me his apt + maids + fees was 1300 a month. Now he's saving about 700 a month by living with me. He was just throwing money away IMHO.
I think rich is mostly relative, even having reasonable goals I think I would need to make about 200k a year to satisfy all of them. So pretty much doctor/lawyer money.
