They could regulate and pass laws. They just don't want to. And the excuse about democrats is not believable, since democrats didn't wanted to pay for the wall and that was passed. If there was a will, they would sacrifice other things to achieve that goal. In fact, they have done that to ban abortion in Texas. And they have been lobbying to get that. Because they really wanted to ban abortion. But they don't want to regulate healthcare prices. It is a choice.
