This is how the greedy insurance companies are squeezing the hard working American citizen. Forget about the blood test, every single type of medical treatment in the US costs as much as 500 to 1,000% more than what it costs in the EU. A surgery which costs $100,000 in the US can be performed for just $15,000 in Belgium, or $10,000 in Russia. Only one solution for this. Nationalize the healthcare sector.
You also have to wait a lot longer to get the same procedures, sometimes resulting in a surgery being unnecessary because the patient has either died or the problem has become so severe that surgery would not be effective.
I don't think you understand that if you make these things cost less unilaterally then the people who perform these services will ultimately get paid less which would mean less people would enter the field and those that do enter the medical field will be less qualified.
