The reflex to make complex laws/tax structures more complex usually accrues benefits to the bigger players more able to parse, navigate and arbitrage those structures.
Every time US tax code gets more complicated, it usually doesn't help the bottom 50%.
That's true to an extent, and overall I agree that things should be simplified, but I think there's a special case when the "complication" is something like "if you are bigger and more able to navigate this, you must therefore pay more". Create a feedback loop where increasing resources automatically result in higher fees and fines.
But when you don't do that, you run into different problems, which is what we have run into already.
