You effectively get double taxed. But the government bureaucrats need silly money to spend.
They could supervise things better and act more effectively but why?
The average Joe taxpayer has no lobby and can be milked whenever lack of funds arise.
He is then rewarded with lower pensions than most public servants.
Same goes for property, depending on the country you live you can be taxed up to 4 times:
1. Pay tax on income
2. Pay tax for acquiring property
3. Pay annually recurring taxes
4. Pay tax when handing property down
