isn't taxation, in this case, a type of government enforced savings :)

So the gov. could force people to essentially provide for a level of healthcare for everyone.

Also on the Obesity point, if the UK was a US state we would rate somewhere in the middle of the pack on obesity levels.

Yet the UK pays far less per capita on healthcare and provides a basic level of healthcare free at point of use (rich people are free to increase that if they want)
