Yeah but those aren't groups I have to deal with unless I choose to. You really can't get around the financial system. It's not like I can take a 100 bucks and walk up to say a gas station and say "1 share please". And before you say Robinhood keep in mind that you don't actually own those stocks, they own them and you are just "managing it".
I mean most are just greedy cuz the field attracts those kind of people. You'd be surprised how many people have next to no financial literacy and a GOOD financial expert can do legitimate good for these people.
The financial industry is, ostensibly, about connecting people that need money to people that have more than they need. In practice it's about skimming from the top of EVERYTHING in society.
