Regulation of things like pollution serves the interests of the people broadly, but undermines the interests of a handful of obscenely wealthy sociopaths.
And much of the current Supreme Court explicitly works NOT to serve the interests of the people broadly, but to serve the interests of the obscenely wealthy sociopaths.
And that's it, right there. Just as has happened in numerous past civilizations, the power structure in the US has become so warped and corrupted - so entirely in the control of sociopaths - that it not only no longer even pretends to serve the interests of the people, but tends to explicitly work against their interests.
And the hell of it is that the ruling class is so far gone in corruption and shallow self-interest - so sincerely deeply mentally ill - that they don't recognize that ultimately they're working against their own interests - that serving the interests of the people maintains the health of the society from which they benefit, and that working against the interests of the people undermines that health. Like any other mindless parasite, they're going to destroy their host, and in so doing, ultimately destroy themselves.
And the US will just be added to the ever-growing list of societies destroyed through the machinations of a relative few profoundly mentally ill people granted undue wealth and power.
