It's not being given away. How are the roads, police, schools, defense budgets funded?

I just checked. The US and the UK both have a 4.1% unemployment rate. Many of those people are unable to work at all. our social security net means that if you're disabled you shouldn't end up honeless. Note it also pays for healthcare, so there's no chance of me being bankrupted from being hit by a car.
