You really don't understand how non-profit works, do you?
Even going by your views it is very easy: Hospitals have lots of real losses. Every time a homeless patient walks into the ER and needs surgery that's real loss. Not because of the difference in billed and contracted rates but because the hospital spends real money (i.e. pays wages, electrical bills, OR equipment, medications, etc.) so their loss goes up but income does not (no re-imbursement from the homeless patient for even a dollar). This offsets the income from a paying patient on their balance sheets.
Again, I ask how does any of these arguments justify paying more for a tradesman just because it is after hours? Which is what I took issue with originally and set you off.
