How so, bro? I find it ironic that the only people who usually peddle this big bad government / taxes are bad have little-to-no understanding of economics or the cost of the services they provide. They are more efficient, yes. I also don't know how you expect people to afford or have the time to pay for all these services that they may or may not use.
Show me a respected economic theory that states a command economy is more efficient than a free market. Better yet, show me a real world example.
As for how people will pay - well, not paying a quarter of their wage in tax would be a start...
And when there isn't enough charity these people just what exactly? They die... freeze/starve/bleed to death etc.
And what will happen to these people when the state realises its inevitable bankruptcy?
