Their argument for abolishing the tax seems to be (a) it's not a big contibutor to GDP, (b) businesses might raise employee wages, and (c) we can control corps with other regulations. Reasons a and b seem to conflict. If corps already aren't paying tax, they have the cash ready to raise wages. Reason c ignores that there are similar loopholes to safety and environmental regulations too. Taxing corps is an answer to the problem that companies cost the government money (i.e. trucking companies use roads) while benefitting the state (employing people who consume and pay income tax). Maybe it's a good idea for the government to directly recoup the benefit of a company using state resources.
