I think companies that pay high wages to their blue collar workers should pay less taxes.

they would... because the involved increased labour cost would mean they make less profit

in other words: profits should me taxed more

I also think companies should publish the ratio between the highest paid employee and the lowest paid employee. how fair is your company really?

Depends what you mean by high wages and less tax.

If increasing those wages costs an excess 1 million to the company but in return the company gets a 50 million dollar tax break, I would say hell no.

So what is high wage to you
