@maxxcan Take the UK for example: roughly 2 trillion GBP in GDP every year. About 800 billion in tax receipts, representing a state that is 40% of the economy.
The historical norm, for the last 100 years, has been that the state is about 35-45% the size of GDP, in terms of spending. The UK has vast public and private sectors providing very high quality goods and services.
Of course, targeted assistance to help the most vulnerable is the good and proper thing to do, regardless of your politics.
