Of course it didn't affect the corporations, it affected individuals. The companies aren't spending any more on health insurance, it's the employees who are spending more and getting less. This has been proven over and over in the last few years. Companies don't have to care though: what employees do with their pay is of no concern to them.
America needs real healthcare reform. Reform that actually provides healthcare, not insurance. The ACA was written by lawyers for the major health insurance companies as a way to force more people to buy health insurance that costs so much while providing so little benefit with deductibles upwards of $6000 per person (and upwards of $12,000 per family) that no real people get any benefit from it. Meanwhile spending continues to increase in the healthcare sector in order to get our already very poor health outcomes. It's a travesty.
