Actually as far as health insurance hikes go... if it weren't for them ordering an MRI every time someone stubs their toe (do you have any idea the ridiculous cost of running an MRI machine -- we're talking thousands of dollars every time it's turned on), if it weren't for them running reams and reams of tests that are unnecessary when there are cheaper and more effective ways of getting results, if it weren't for people getting their doctors to do a housecall when they have a sore throat, if it weren't for people going to their doctor because they just have a sniffle.... these are the things that would stop the hyperinflation of medical insurance costs.
If there's one thing you learn growing up with a doctor for a stepfather (and cousin, and sister etc) in a country with public healthcare (Canada) you learn not to abuse the system. The amount of abuse of the system when people have the attitude "well I'm paying for it, I might as well use it" is ridiculous, and of course of complete benefit to the private holding companies.
