2/The first good thing about capital gains taxes -- as opposed to corporate taxes or payroll taxes or sales taxes -- is that you can make them very progressive, so they mostly tax high earners.

Biden wants to do exactly this.
3/The second good thing about capital gains taxes is that they won't throw the country back into recession.

Capital gains taxes are macroeconomically safer than most other kinds of taxes.
6/And how about the impact on real business investment? There's evidence showing that dividend tax cuts (which are sort of like capital gains tax cuts) don't boost business investment.

7/In fact, capital gains taxes could even STABILIZE financial markets by discouraging over-trading, thus making them more attractive places for long-term patient capital to invest.
8/But capital gains taxes DO raise a lot of revenue.

A recent paper by @NatashaRSarin, @omzidar, et al. shows that these taxes are good at raising money: https://www.nber.org/papers/w28362 
9/And in the end, on top of all these economic benefits, capital gains taxes probably seem very fair to the American people.

Perceptions of fairness matter a lot!
