That’s just it, the system was created as a two-party system, and two-party is a hugely beneficial to the champions of that same system who make the laws, the same people who would have to make the law to change the system to make it harder for themselves to “win” but better for us.

You would have to have people in charge who were willing to give up their power to make things better for the people as a whole, and sadly there’s basically nobody left who gives a shit about the population as a whole. They’re all selfish as shit. About half are currently more evil, but they’re all out of touch and working for nobody but themselves and their wealthy benefactors.
