He\’s still not really got it:
As a result tax burdens are shifting from companies to ordinary people, whose effective taxation rates in the UK have risen as corporate contributions have fallen.
He\’s missing the idea of tax incidence. Sure, it looks like the corporations are paying all of that tax. But they don\’t really. The corporate income tax is paid by investors, by workers or by customers: the company is just that convenient legal fiction that the cheque comes from. As is detailed here.
Which is why we should abolish coproation tax altogether and simply tax the income when it arrives with the workers or the investors.
