opinion that taxes on income are a bad idea

Do you mean earned income, aka labor? vs unearned income, aka capital?

If you are advocating the shift of tax burden from labor back unto capital, reversing policy of the last 35 years (Reaganomics), then I agree with you.

>unearned income, aka capital

capital isn't unearned - it has to have come from somewhere (perhaps the grandfather generation).

It's a technical phrase, not a value statement.

Unearned income refers to income received by virtue of owning property (known as property income), inheritance, pensions and payments received from public welfare. The three major forms of unearned income based on property ownership are rent, received from the ownership of natural resources; interest, received by virtue of owning financial assets; and profit, received from the ownership of capital equipment. As such, unearned income is often categorized as "passive income".
