You will never get "rich" by working, there is no job that will pay enough, unless you're the CEO of some huge multinational. For 99.99% of people, the only way to become wealthy is through investing. Say property, stocks, business or whatever. But working (anywhere) just won't do it
Yes, you could have married someone richer, however, even that comes at a price because "high value" men are always going to be chased after, and you will spend your life looking over your shoulder at the younger, prettier women who will try it on. Age old story of the "slut half his age" kind of thing. And yes, you might get a huge divorce settlement if things go south, but it's still a shit situation.
I think money is a strange thing, you read surveys that say 60k a year is peak happiness, beyond that there is no direct link between money and satisfaction. I earn about that, and maybe there is truth in it. When I think about it, if I had more money, married into it, I suppose I could drive a Bentley instead of a BMW, but I don't think it would be that different TBH, so I'd probably not be any happier IUSWIM.
I could get a Mansion in Surrey, but empty rooms freak me out a bit and I'd hate to have strangers (staff) around my home, but I wouldn't be able to keep a huge mansion clean and running by myself. So, there's that.
I think everyone "settles" in the end. You would "settle" for a wealthy man you don't really like, just to be "rich". Or I might "settle" for a low income, ordinary guy, because he is willing to have children with me.
It's all relative I think. And I guess ultimately, you'd always have the "my yacht is bigger than yours" dilemma. You know, there you are in your new BENTLY, off at the races, when a really rich guy shows up in a helicopter. And you'll think, fuck, I should have married him him instead, my husband can't afford a helicopter.
