> Both political parties have multi-decade track records of aggressively supporting pro-corporate political agendas at the expense of their constituency
Someone only tuning into general elections and making this complaint is either not intellectually there or plain lazy. Very few places in this country have zero competitive elections on the ballot. And none exist where calling electeds and showing up to advocate don’t move the needle. Doing those things takes effort, however, and I concede that for a lot of people that effort isn’t worth it since they’re comfortable enough—personally—with the status quo.
The flip side is that leaves a lot more room for everyone else. It’s genuinely surprising how accessible power in America is once you start wielding it. That sucks when nobody is watching but a few paid interests. It gets interesting when you find yourself, repeatedly, as the only person in the room with the levers.
That elections are "competitive" is utterly irrelevant in a political system where local, state, and federal legislation is almost exclusively drafted by lobbyists. Lobbyists who in addition to supplying pre-written legislation also supply staffers with pre-formatted position statements to distribute to anyone who bothers contacting their office about said.
In practice that "competition" you seem so taken by produces nice sound bites and some column inches on whatever culture war rag is being waved in the face of the citizenry, and literally nothing of substance that addresses any of the myriad slow burning economic and systemic crises that have been building for the last 40 years.
Using agriculture as a microcosm for the larger economy there has been nothing proposed much less ratified to address the complete chokehold Monsanto, John Deer, Cargill, and Tyson Foods have on every aspect of the agricultural industry . And they've had literal decades to make a move.
Princeton University released a study 16 years ago that concluded the US was a de facto oligarchy and if anything legislative capture has only deepened in the US since then. Hell at the local level I've watched the county planning board float a ballot initiative to greenlight a major construction project which was soundly rejected by local voters. Net result: 5 years later they broke ground on the project anyway. So you can tell me there's movable needles out there until you're blue in the face, let's see some reciepts.
