No it would not be workable, in the same way it became unworkable in Russia.
Money does not just come out of thin air, it has to be earned, generated.
The only reason we can have a health service and all these government departments is because people earn money and pay a lot of tax.
If you take a poor country, where there is a low wage (in Africa for example) then the people earn such low wages they could not afford to pay much tax, and therefore the services provided by the state are very low.
Even in the USA, which is a RICH country, but a LOW TAX country, the state provides far less services than in the UK and other European countries.
This is why so many immigrants and asylum seekers some here. We are very easy going with handing out our benefits (like using the NHS) so people see us as a each touch.
But it all has to be paid for, and with an ageing population who dont work, and many well off people moving abroad (and hence not buying anything in the UK) we are mostly left with chavs, and people who are scounging.
It will all come down on us soon, when our personal debt gets out of control and all our jobs go to India and China.
