What is it about if not income?

[seanmcdirmid]

Income is what you earn from your labor (the things robots will do in the future). Capital is setting money to make more money (e.g., by buying robots to get rid of labor that earns income).

[ceejayoz]

Wealth. You can be fabulously wealthy without an income.

[bigmadshoe]
