Re: Tax isn't my strong point...
You are quite right that making money is one of the main things that incurs a tax; but not that make money=pay tax. Spending money is another main thing that incurs a tax. Or living somewhere. Or dying. (I'm retired, obviously...).
I do like your point, but I'm not comfortable with the idea that behemoths provide their services for free. They use, or exploit, our tax-funded infrastructure: like education, for just one example.
