The pie chart is confusing me, why the box for health is bigger, with higher percentage of 43% and you call that smaller tax, from the chart you could tell that transportation sector has the least percentage of 0.2% of taxation, why is that, or am I reading it wrongly?
If that's the case, health sector is wealth, when health is shattered, then the free access to get treated and taken care of at first sight is guaranteed, as that's the step n the united states of America.
The chart doesn't represent taxes realised from these sectors. It is only a representation of subsidies and tax preferences for different areas. It shows that government is spending more funding financial mechanisms designed to lower the cost of medical care and health insurance than its is doing in other sector.
There have been reports of fraud in the health sector of the US. The government might not have to spend this much on subsidies and tax preferences if corruption is reduced in this sector.
