For the most part, rich people produce far more than they consume. Poor people consume far more than they produce. Consumption inequality is vastly lower than income inequality.

I'm opposed to income tax as well. A consumption tax is the best tax, since it's both a) hard to dodge, b) transparent and c) doesn't penalize investment.

In principle an income tax is equivalent to a consumption tax, but in practice taxing labor income but not capital income induces all sorts of tax avoidance schemes that treat labor income as if it were capital income.
