I am skeptical of hypotheses like this when the deterioration has begun before its supposed cause. This is how I look at social media or tinder being blamed for loneliness or low fertility. While they may have exacerbated the issues, trends have been unfavorable for decades if not centuries before.

Similarly, it seems to me like the rule of law (and the separation of powers), prestige press, and universities are social technologies that have been showing more and more vulnerabilities which are actively exploited in the wild with increasing frequency.

For example, it used to be that rulings like Wickard v. Filburn were rare. Nowadays, various parties, not just in the US, seem to be running all out assaults in their favoured direction through the court system.
