Higher tax rates on big businesses or corporations, makes them wiser, makes them run their businesses more efficiently....
From experience, when the corporations decided to allot me less money in my budget than they did last year, while still having to beat last year's profits made...I had to really put my thinking cap on and figure out how I can do this in my area of business... And other Buyers and Merchandisers had to do the same.... From cutting waste in supplies, in travel expenses, and business dinners, to working a better deal with the vendors I bought from was all touched....and low and behold, the lower purchasing budget still worked out to the higher profit they expected with less money to make it.
Same thing with corporate taxes being raised or at high levels...it forces corporations to waste not, run more efficiently while still providing stock holders with their profit. They spend their money on things that bring their overall taxes down, like investing in expansion....which is tax free, investing in their employees, with raises or an increase in hires, because it is tax free....they would rather spend their money that way, giving them a future, than giving the govt 40% of their profit.....
