Seriously, you're not making any sense here.
For the third time, it's not about earners it's about assets. How can you keep blurring what's actually a very clear distinction?
The executor can't make up a value for the assets of a liquid, marketable asset like a stock. The date-of-death valuation is held and the estate is forced to sell to raise the cash if needed, even if those gains are all unrealized stock market gains.
The income tax assumes what you said before, that someone making money is doing well for themselves. An asset tax is like a property tax, it just sees a big pile of gold and reaches out for it.
Why should people be forced to sell their assets before they die? Why should we actively try to prohibit significant long-term capital accumulation? Especially in the US, where we have so many African-Americans who are becoming wealthy for the first time in the history of their families. To discourage that money from staying within their communities seems to be especially...quizzical.
Because they are your kids and it's a single family unit. Taxing exchanges between them is silly.
