Earlier quoted context omitted.
That seems like the way the incentive is supposed to work no? Motivate the economy by furthering investment back into it.
If we tax wealth, people will be incentivized to generate non-wealth things. Why buy a stock if Biden will take 1% of it annually? May as well just buy rapidly depreciating status symbols instead.
Because the stock will allow you to avoid paying taxes. By investing revenue in investment, as a company, you can avoid paying tax on the money. So if you're a small or medium sized business, you have two choices:
1) Cash out and buy a rapidly depreciating status symbol with the money, but get taxed on it at a higher rate.
2) Reinvest the money in growing your business.
At least that's what I understood from OPs reasoning.
Edit: Also spending money in depreciating status symbols is also a contributor to the economy.
