I feel like the best way to fight this, if I was the government, would be to stop enforcing laws preventing patients and even doctors or hospitals from importing the overpriced pharmaceuticals from overseas generics manufacturers. Like the article points out, each pill costs no more than $0.25 to make. The goal wouldn't necessarily be to get everyone using overseas suppliers but to put downward pressure on the price gougers in the country.
Maybe if Pharma companies didn't get so rich already, this could've been possible.
Changing the law will take time (election cycles). If you cannot leave the US for a developed country that won't squeeze to extract from you while you're trying to meet your healthcare needs, importing your drugs that can be imported without US approval is your only path in the short term, or potentially traveling to obtain them and bring them back (roughly two-thirds of the entire U.S. population, ~200M people, live within 100 miles of a U.S. land or coastal border).
