They never said they'd adopt universal healthcare like all the other western nations. I personally belief we should adopt it, since our healthcare system is right up there with Morocco and Costa Rica. We have the lowest life expectancy out of the entire Western World. Universal healthcare isn't about politics, it's about ethics. The only reason we don't yet have it is because of constant lobbying and bribing done by the health insurance industry. Ever seen these little shows on things like Fox and NBC where they go on about how evil it is? Completely ridiculous.
Anyway, the Obama administration has stated it just wants to make health insurance affordable again. During Bush's term, Bush had deregulated the entire industry, causing prices to skyrocket, so only 1 in 3 Americans could afford health insurance. The industry needs to be regulated once again, so the insurance industry can no longer gouge Americans for all their money.
No one should be denied medical treatment, it's unethical.
