The whole stock market is built on the premise that you don’t have to work for the company to benefit from its success. Why is a family’s success any different?

The whole stock market is built on the premise that you don’t have to work for the company to benefit from its success. Why is a family’s success any different? If a parent works hard, makes money, pays his taxes and wants to give that money to a child, it seems obscene to me that the government steps in and takes yet another cut of the money. The parent paid their income taxes on the money already. I believe in his death he owes capital gains on his stock holdings. So all the money that’s passed down has been taxed fairly already.
