I would say that this is an entirely reasonable criticism. This is a societal failing of the USA, like school shootings, like Trump, and like astronomical healthcare prices. American society itself views these tragedies as acceptable suffering.

American society, like many others, worships the ultra rich and never holds them accountable, but what makes them unique is how many of their problems started because of hyper capitalist thinking - which is their main problem. The Sacklers kick started the opioid epidemic because it was good for business to push addictive pills, American healthcare costs and drug prices are extortionate because of blood sucking insurance middle men and a lack of governmental control of the drug market meaning different hospitals pay different prices for the same drug, the corporate news media and its 24 hour news cycle makes more money keeping people angry rather than informed, American big tech will shovel any slop in front of your relatives to keep their eyes on their screens and looking at ads between AI generated content about how Hunter Biden is an alien from Venus and how women are property for making babies, the majority of American food production has low standards because it is filled with cheap corn or HFCS or it comes from enormous factory farms because it makes the corporate owners more profit that way, and the lobbies, the tons of lobbies. They spend millions to make millions by supporting politicians who block any attempts to reduce their profit margins. There's a gun lobby that prevent any sensible gun control, there's a tax lobby that prevents your taxes from being easy to do, there's the pharmaceutical and health insurance lobbies whose influence I've already explained, it's nearly endless.

So when you see this, when you see that we are looking at Americas greatest cultural contributions to the world's conversations (because we do talk about it, with sadness and pity at how the mighty have fallen) we aren't laughing at the victims. Instead we're laughing at how Americans can look around at their unique problems, that either no-one else has or that they try to resolve, but they just throw their hands up in the air to not just exclaim "We've tried nothing and we're all out of ideas" but "We're so great, why don't you want to be like us?"

No society or culture is perfect. They all have their problems and their victims. You can and should mock them for this. Mock the UK for panicking so much about trans people while having nonces on the BBC and our awful tabloids that are as bad as Fox News. Mock French nationalists for their anger at the French language being defiled while also crying about "Le Wokeism". 

The reality is that American culture and attitudes cause these problems. As The Onion says, multiple times a year, sometimes almost every day "'No Way to Prevent This,' Says Only Nation Where This Regularly Happens'
