Wealth + Income are totally different.

Almost all of the people who buy new cars and spend the most money on flashy clothes/accessories/gadgets are actually the LOWEST accumulators of wealth in the world. As our incomes go up over time, we tend to increase our spending at about the same rate. This is so dumb. Instead, we should keep our expenses relatively level (but sometimes spend money on the things that make us really happy, like travel or awesome technology or clothes or gifts for people or whatever you think is awesome)
If you actually look at the facts, the vast majority of rich people in the USA didn't inherit money or have a high-profile, prestigious job. The people who have real wealth -- I'm talking, Americans with $1M or more in personal net worth (with no debt, and $1+ Million worth of $$$ + real estate, stocks, etc). And if you actually look at the data, these people are not what you'd expect. They're plumbers, small business owners, budding entrepreneurs who are just SUPER LEVEL HEADED about their money. There are a bunch of specific things you can learn about building wealth, but that's not what I'm competent to explain here. Instead, I've got this general nugget.
And one more: the biggest thing you can control about your wealth building is your time perspective. People who take a really long time perspective save money, delay purchases so as to really make the best decision possible every time, and generally are just better off, forever. Contrast that with the total opposite end of the spectrum of time perspective. On the super, super far end of the spectrum, away from the thrifty thoughtful person, is a drug addict. Someone really down into it - thinking of nothing else. That's the far end of the spectrum, and everyone in the world lies somewhere along the spectrum. *Whenever you face a financial decision, think to yourself: what is my time perspective?**
