Wealth, as in money. As long as you have money, you can handle everything else. Money is insanely important in todays world, because only some people have it. The issue is that, what we consider "rich" these days, some of these people are not even rich in old times sake.

If you have a good home, a car every 3 years, kids do not need loans for education, travel to vacation every summer, have no medical bill problems, go to eat every weekend, that is a very rich person in todays world basically. In comparison, that was the "middle class" back in the day, today, the rich are the people who "bought a Yacth that has a Yacth in it" type of people, the guys who have 8 billion dollars, not 8 million dollars. So you need to know, when I say money, I mean really a lot of money.
