Any tax reform that does not address the fact that investment income is taxed more or less flat compared to labor which is taxed progressively is missing a huge opportunity to tackle income inequality and making the wealthy "pay their fair share".
- Lower the corporate tax rate significantly. This creates more value in companies and possibly a larger labor pool.
- Install a progressive tax system on capital gains similar (larger standard deduction than labor) to how labor is currently taxed. Investors are making more on companies that pay lower taxes now. If investment is your sole source of income you'll actually be paying your "fair share" now.
- Lower taxes on working people who spend most of their income. This creates more consumption and investment which leads to better markets.
