Hardy seems worth reiterating as it’s always in the news, but the US seems like it’s in overall decline for most any reason you can think of. Rising disparity, falling buying power for the average person, stagnant wages, increasing costs, rising political instability, rise of the far right with literal calls for civil war, rise of the far right looking to tear down any social, environmental, educational, or scientific advancements, the steady march towards oligarchy and corporatocracy, and then there’s the global climate crisis speeding up and the realization that we’ve been lied to about saving the world with recycling and EVs while the corporations rake in billions and pollute remorselessly.
30-40 years ago the economy looked steady, you could save the world by filling the recycle bin, and you could afford an education, home, and maybe retirement if you followed the “go to college and get a good job” path that generations before had followed.
Subjectively and objectively I’d say we’re worse off.
Sure, there’s some potential bright spots. Advances in medical care (that you probably can’t afford), fusion power advances (that will probably arrive too late to do any good), rising renewable energy (fought every step of the way by anti-environmental types), and a resurgence in the labor movement (also fought every step of the way by the wealthy and corporations), at least that’s something.
