A constitutional amendment would be ideal, but it's critical we never allow a full Constitutional Convention (ConCon) to happen, because those have lower ratification requirements than the regular amendment process and any amendment can be introduced regardless of what they originally set out to pass, and I'd be worried that corpo Dems like Schumer would get tricked into going along with one in the name of a "bipartisan win", and we'd be well and truly cooked.
This was all a pointless exercise. Like, I’m glad Dems fought back, but how much taxpayer money did we spend to arrive at the status quo?
Unfortunately, we're not quite back to the status quo. The fact that Dems went a different route means that the DOJ could sue the Blue states claiming that ballot initiative changes aren't valid but legislature-passed ones are, and then tie everything up through the midterms with SCOTUS's help. Ideally we'd have 3-4 Blue states also do legislature-passed laws that directly mirror Texas'.
Prefatorily, this is entirely my personal speculation based on examining media in the US versus other countries, and my admittedly minor knowledge of history.
Anti-intellectualism did ramp up in institutionalized education in the 70s, especially with the explicit codification of jock vs nerd, but imho this really started as an unfortunate (and later exploited) knock-on effect of anti-bourgeoisie sentiment after the Great Depression and post-war era. The "All-American" working class man stereotype being contrasted against the intellectual is something that didn't happen in e.g. late 1800s France's anti-aristocratic and anti-bourgeois streak; people viewed themselves as just as capable of matching the intellect of 'elites', rather than turning intellect into a negative attribute.
When we allowed the negative depiction of intellect to permeate entertainment media (in the 50s and especially the 60s), it really set the stage for the current anti-intellectualism we're steeped in. We start teaching kids from a young age that trying to be good at anything artistic or anything knowledge-based is cringe, or nerdy, or something losers do. I've lived in other countries, and you don't see that same effect, even in 'macho'-driven cultures.
