Well, in the US, we are in a bull market since 2008! That is 16 years. Obviously there is a lot of money sloshing around. If you kept a job in the US for this time (which is NOT a given I must say), there is almost nothing you can do wrong if you have invested in the stock market.
I have learned that all party eventually end. I do not know when this one will end, but it will.
