Lowering corporate taxes helps people because corporate taxes are across the entire sector and thus are more easily priced in (because your competition is also likely to do so). Consumers pay for the majority of every corporate tax increase.

Wages can be increased through encouraging unionization, passing single-payer health care, etc.

Lowering corporate taxes may have some slight impact on merit pay and even wages as a whole, but it would almost certainly be focused on white collar jobs. I’m not opposed to that, but it isn’t a primary concern
