By many estimates, Medicare has about 2% administrative overhead, which means that 98% of taxpayer's money goes to health care.

The for-profit health insurance industry is estimated to have on average 17% overhead, and often 30% or higher, so that as little as 70% of YOUR money goes to health care. 

That is, if the white male insurance executive decides you deserve that health care in the first place. 

This is the scenario that Republicans look forward to while dismantling Medicare, Medicaid and the Affordable Care Act.
