BTW, I still get new glasses when I visit Japan. About $100 to $300+ depending on the frames you choose, and the eye exam is included for free. This is without insurance (I got 2 new pairs last year, for about $400 total), and I've not lived or worked in Japan in over a decade.) Thinner lenses than in the USA, but perhaps not as safe. The store is called "Megane Ichiba", and I believe it is a chain.
Point is though, that the glasses market in Japan is not as monopolized (or at least not as greedy) as the market in the USA.
I don't think it is as simple as that. Fox "News" has been informing republicans' world view for like 30 years. The Supreme Court has basically been taken over by partisan Republicans, which is super ironic given how long and loudly republicans railed against "activist" judges.
Much of the used-to-be credible media is now owned by billionaires. Even the ones that aren't want to at least keep their access in the event of a Trump win.
Trump did significant damage in his first term, but, as the cliche says, "the guardrails held". Thing is, he learned both about those guardrails AND which people he could trust to choose him over the Constitution.
So, yeah, there are things that should be done to make the system more resilient to internal attack, but without significant time and effort, no majority of USA citizens will every be convinced to support that sort of change.
