Countries differ in the levels of taxation. In general higher tax countries are healthier. No surprise. If we argue and debate and agree on something useful we might agree to fund it from taxation. In general then the things we buy through taxation are well considered and worthwhile. Contrast that with private spending - impulsive, ill considered purchases of largely trivial goods and services - the vendors of which laugh all the way to the bank. Higher taxation encourages us to spend a higher proportion of our income on worthwhile commodities and less on ephemeral nonsense.
Think about it!
