Universal Healthcare

So, is anyone else tired of the crap argumentative finger pointing in congress?
These are the real questions (they do show my ignorance in this topic):
Does the current healthcare system work?
What are the problems with its current state?
How many people need healthcare that can't afford it?
How many people can afford it but would be better off with something else?
Is the uninsured number being overstated?
What percent of the population is uninsured?
Is healthcare something that should be guaranteed?
Can we require that doctors take the Hippocratic oath to treat everyone to the best of their ability even if they can't expect payment?
Is the insurance industry over/under regulated?
Feel free to answer any relevent questions that I haven't asked, too.
Thank you
