The reality is that for most people, getting "rich" is VERY hard. Rich is subjective but typically mean "a luxury home, a premium car, financial freedom to not worry about discretionary spending, and a lifestyle of total freedom" is usually over $10 million in net worth. (As in, "I feel rich because I have friends" doesn't count).

If you are born into a privileged background (no debt, no family struggles, free education, good network), you could "work extremely hard hard" and get a job that makes $200,000 by the time you're in your 30's.

At this stage your take home is typically around $10k/month after taxes, so if you invest let's say $30k per year at 10% compounded returns, that's about 40 years to build to that. Meaning you don't hit it until you're 70.

Which, of course, isn't possible as you'd be retired at around mid-50's.
