It sucks. I can pretty much summarize the place into two topics:
"I am a broke high school/college graduate with no money, what do?"
"I have a job offer of 100k in Low Cost of Living or 150k in High Cost of Living. Please help me, which should I take?"
And every other response seems to be written in the eyes of an autistic person who makes 200k and views making friends and enjoying life as wastes of time. You shouldn't be racking up debts and living irresponsibly, but your 20s should feature at least a little bit of fun. You're never going to have that youth and freedom again.
I would never ever take financial advice from reddit. There is no silver bullet for wealth. Not really sure what that sub could really offer anyone.
