so Why medical bills are so high :
Instead of being a tax strategy, high hospital charges are driven by a complex mix of factors:
Negotiating power: Hospitals set high "chargemaster" prices as a starting point for negotiations with insurance companies, who then negotiate for substantial discounts. The sticker price is rarely what an insured patient or their provider pays.
Cost shifting: High prices for some services or patients help cover the financial shortfalls from caring for Medicare and Medicaid patients, for whom reimbursement rates do not cover the full cost of care.
Covering losses from the uninsured: High charges also help compensate for the costs of care provided to uninsured patients who cannot pay.
High operating costs: Labor costs, new technology, and pharmaceuticals are all major expenses for hospitals.
Administrative costs: The complex, multi-payer system in the U.S. creates substantial administrative costs for billing and coding.

and basically, the insured help pay for the uninsured and those who dont pay their bill...( like the US paying for illegal alien healthcare- it aint free..and we all pick up parts of the tab...kinda like slackers hitting a bar and order way more food and drink than they can pay for and then passing the hat to cover it..restaurant is ok collecting most of the bill and thrilled they left...seen it around here a few times)
