Finance is about money, that's going to attract some people that are motivated purely by money. That's a bad thing and the culture in any institution should discourage this.

Yet at the same time finance is a big industry, there's plenty of honest, hardworking people that do their 9 to 5 (or more realistically 8 to 7) and go home to their kids. Finance has bad apples (just like tech) but I don't think we should write off the entire industry for that.
