Utltimately, we're not talking about morals, we are talking about state finances. This is measured in pounds not happy thoughts.
The morality comes from believing it is a good thing to give money to the state, how does recycling money from the state achieve anything?
So, we need a government to, well, govern.
So how do you propose that works if taxes aren't partly used to fund the wages of those who govern? I'm sure privatisation of the government would work out just fine....
And anyway, recycling of cash is a good thing, liquidity is key to a healthy economy, we pay taxes, they pay him, he uses that to pay for stuff, we make money from him, we pay taxes, ad infinitum.
And I don't understand how you see his job as any different to that of a fireman or policeman, they're ultimately jobs that need doing but that no one would actually want to pay for directly.
"Hello, emergency services? I'd like a fire engine please, my children are in a burning house."
"Can you please provide the long number across the front of your card, the expiry date and the security code. Then I need to read out the T&Cs before I can despatch anyone to help, sorry they're so long but for legal reasons I need to do this......
OK that's all gone through OK, but as we have to make a profit for our shareholders we don't just have people sitting around, I can get an appliance out on Monday morning."
