The statement is taken out of context in order to bash a politician. Not that I care about any politician, none of them can be trusted. I won't participate in the bashing.
He was talking about the denial of coverage by insurance companies.
There's nothing in The Constitution that prevents the government from passing legislation that regulates a business. Were anti-trust laws given the same scrutiny?
I do find it difficult to swallow that the government is forcing people to purchase a product, by law and with governmental penalties, that is solely provided by private industry with no government alternative.
All of this could have been avoided had the insurance companies not been greedy bastards. If someone is insured with you then pay the bill when they get sick. Some were notorious for denying what they promised to cover. Dropping coverage after a person gets sick or pricing the insurance beyond the person's means to force a denial of coverage is also not fair. Insurance is a risk on both ends, not just the insured.
The other beef I have with the health care is the way insurance companies get special billing privileges. They pay a fraction of the price for services, prescriptions and medical devices. Private patients make up the loss by paying higher prices. Insurance companies can pay a bill whenever they choose to pay it, even if it's 6 months from the date of service. Private patients must pay their bill at the time of service.
Hold insurance companies to the same standards as private patients and you'll see a reduction in health care cost.
It makes "Medicare for all" look good, quite frankly.
