About half the states have already passed tort reform and there is zero evidence that it has reduced health-care premiums in any of them. So that't not a solution to Obamacare's costs.
I would ask exactly what they passed, regardless of what they called it.
Most politicians are lawyers. For the most part, they will not pass anything that threatens lawyer’s incomes. Lawyers might have passed something they called “tort reform” but really wasn’t.
It would be analogous to when there was a call to deregulate utilities in CA (in the 1990s). The lawyer-politicians made a big show out of “deregulating”—but in reality, they deregulated nothing. All they did was institute a new and different set of regulations and called it “deregulation.” And then, when the alternate regulation didn’t work to lower prices and so forth, they gloated that deregulation doesn’t work.
It also would be analagous to immigration reform. The people want immigration, especially illegal immigration, curbed. So the lawyer-politicians think of all kinds of goodies and benefits to give to illegal aliens, and call it “immigration reform.”
I could go on and on, but I think you probably get the point. What we, the people, call reform is usually an excuse for lawyer-politicians to write more laws benefiting themselves. They don’t institute the reforms that the people actually want.
