Do we then drop corporate income taxes? One reason capital gains is lower than income is because the value was also taxed on the corporate profit side. In order to make investment more appealing capital gains is thus set lower to offset the double taxation on the growth.

AFAIK many (if not most) do this for this reason (and a few others, like capital gains not taking into account inflation, etc.).

It's also why the rich have an effective tax rate about 10% higher than their income tax since they're paying the corporate tax. Here's [1] a CBO report on effective tax rates by income distribution showing this.

Rich people get richer through dividend payments or capital gains. But if they keep reinvesting the capital in their business then they'll be able to defer tax forever..

You can reduce inequality by limiting the wealth you can generate from a corporation.

In some places. And the new tax bill placed caps on those, so living in high cost of living areas, because that's where the jobs are, means you're probably not going to be able to afford a house.

I don't believe this. People tend to max out what they pay for their mortgage so if they have a tax deduction they just will pay more for houses. Which then benefits the owning class.

If you remove mortgage deduction, I'll buy 10 houses just because others can't use their deductions to offset the mortgage.

There are all cash buyers sitting around the corners.

I advocate for capping the total mortgage deduction.

I agree about capping. Same for capital gains. Put a cap on it that lower income have an incentive to invest.

Capping mortgage deductions would also make real estate "investing" less interesting so the money would go to other purposes than driving up house prices.
