Tariffs are also revenue. It just moves the revenue from income taxes, which can affect the rich if they have incompetent accountants, to consumption taxes, which affect predominantly the poors and middle class.
Tariffs are a tax levied on American consumers, not on foreign governments. Using them to decrease income taxes on the rich is something only an out-of-touch millionaire could dream up. Qu'ils mangent de la brioche!
And the effect of consumption taxes is generally to reduce consumption. The economy is likely to shrink a bit as a result of these taxes. It's hard to see how that helps anything.
