I like the idea of basic income but I don't like the idea of raising income tax. I think capital gains tax should be raised and there should be a special tax on passive income.

All Passive income sources are essentially small monopolies - If you own an asset from which you derive passive income without having to work at all; the dynamics of this are not so different from a corporation having a monopoly over an industry. At the root, why should some people get paid for doing nothing at all while others get nothing. Doing nothing should have the same market value no matter who you are.
