It's true Americans have never been wealthier, however, the wealth disparity has never been greater too than now

The wealth disparity is even worse than it was in the late 1920s which helped trigger the Great Depression with the Stock Market Crash. The buying stock on margin was the worst of the crash which most people don't do now or aren't allowed to do now in many cases. But, I personally have friends that were wiped out in the stock market by being too growth oriented in their stock purchases and one day when they weren't looking they lost everything. So, being an investor (unless you are a long term investor) and a very conservative investor at that, often brings financial ruin one day when they are traveling or busy doing something else rather than watching what their stocks are doing that day. Investing is a fine art and the more you are into growth stocks the more it is like Las Vegas (easy come easy go).
