If our government spent less on bullshit, we might actually be able to have a serious conversation about universal healthcare (while keeping in mind that paychecks would be taxed heavier because of it). It's all about balancing the GDP with the extraordinary cost of such an undertaking. Thus far, no one has suggested anything that wouldn't suck so hard as to become a blackhole on our economy.
Currently, there are already programs in place to cover medical costs for those in certain circumstances. If you're grievously injured and/or are taken by medics to the hospital, you get emergency care with or without insurance, for example.
While a privatized medical field produces unbelievably specialized and skilled practitioners -- so much so that people come here from all over the world for life-saving surgeries and the like -- there probably should be an option for those who can't afford to pay for standard insurance... like Medicare but for younger folks.
There are several issues with that, however. Who would pay for insurance when they could just get a little bit of government provided coverage for free? We've already seen that, when given the opportunity people will take less money to do nothing rather than work for more... I find it hard to believe this wouldn't apply to health care. Also, there's the issue with the service such a system would provide to those who opt in. The free market forces doctors to compete to provide the best service and they their pay increases accordingly. Completely socialized health care yields middling and uncertain results from their personnel... why attempt to do good work or be the best in your field when you'll only be paid what everyone else is getting paid?
But for sure... the conversation needs to be had... at a later date. With what the US economy has coming its way, we won't be able to afford to consider universal health care for another few years.
