Zero Corporation Tax allows multinationals to make huge profits and just chuck the money back home, even if that's outside the Union. Yeah, they're probably paying tax on it somewhere, but it's not taxed in the place it was earned. That's the problem here. Countries are losing cash and tax revenue to this.
Your trickle-down economics is similarly unproven.
I think the idea is that governments should tax things which aren’t as mobile (personal incomes, land, consumption etc) in order to minimise the distorting effects on the market tax can otherwise have. There are positives and negatives to that but it’s not totally obviously bad.
