Taxes on capital gains are taxes on investment. The higher they are, the less returns people or institutions (such as pension funds) get for their investment dollar. And when returns are diminished by high taxes on capital gains, that investment funding will seek friendlier climes to invest in.
Investment drives the economy. Diminish it through ill-conceived policies based on some misplaced wealth envy, and you will see the economy shrink. In the US, those gains were already taxed under the corporate tax, and this is just a double taxation on the earnings - once when earned, and a second time when disbursed.
It isn't about liberal class warfare or whatever, but about economics. There is a reason why almost all European countries have lower (or even zero) capital gains tax - because they know it is economically foolish and counterproductive to tax investment.
Why because the original investment money came from Earnings which are taxed. Then the money is invested and it is a gamble whether there is profit or not. The lower rate is to encourage individuals to invest in real estate, so tenants have a place to rent, invest in business so people have jobs.
Raise the rate and the wealthy will just put their money into Tax Free Bonds and Securities. Which is happening now and that accounts for the almost ZERO job growth in new businesses.
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.
