Take on the Amazon tax rate

I can't say I truly understand corporate taxes but I do know that my company pays them while apparently Delta and Chevron and Amazon avoid paying them. I'm far from a socialist but even I don't understand the justification of this, the idea of taxing corporate profits has been around exactly as long as companies trying to figure out loopholes to get our from underneath paying them.
Time for Bezos to step up and the IRS to start to force him to pay his fair share.
