Not even that. Someone who got laid off by one of Paul Graham's friends likely has decent investments and is receiving relatively small salaries from labor (that is, 0, unless you're counting unemployment insurance, and then, is that saved-up labor pay, delayed and amortized, or "investment" income from your taxes?). And if that person is class-conscious, or at least self-interested, they should be 100% on-board with a wealth tax.
