What you or I want is no longer a question afforded to us sadly.
I'm genuinely curious: Are there periods of history where people could choose what to go into without it having a large effect on their income or quality of life? From my point of view, it seems like our standard of living is at an all-time high and our freedom to choose what we do with our lives is unprecedented. But I'd be open to being shown empirical evidence to the contrary.
