Exactly. If pressured, govt might use that money for welfare although likely most of it will go into military industrial complex anyway. But taxes are not a way of reducing the political power of the capitalist class.

Edit: I’m not arguing against taxation. Better to tax them then not to. But their political influence will not diminish with taxation, if anything they will have more pull by threats of moving elsewhere. Again, definitely do tax them, and the more of it goes to workers the better, but this does not challenge the political system.
