True or false: the stock market more than doubled under Obama's presidency?

No, unless you start out rich, and get lucky. Not all stocks go up all the time and most that do go up only rise slowly. Most dividends (if any) are in the 2% - 4% range.

And then you owe taxes on dividends and any gains from selling the stock.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
