It ignores completely all the tax my (sole trader owned) business pays. We get a hell of a lot less back from the state than we pay.
It also ignores all the tax the company you work for pays out of the income you've generated for it if you're employed in a multi-national company. How rubbish is that?
Do the people on here seemingly complaining about getting less back from the state than they pay really not get that there has to be a significant balance of payment to the state to pay for things like teachers, doctors etc.?
