Many people over here complain about Amazon not paying taxes.
In fact, and I'm sure it's the same in the US, they pay the same taxes as you, me and everybody else, the pay what the tax authorises say they must pay, otherwise they would be prosecuted.
If this amount should be more, don't blame Amazon. No one pays more than they need to. Blame the politicians who make the tax laws, many of whom, dare I suggest, are looking for big business directorships when they to supplement the meagre pensions they will get!
