I mean, the expansion of the universe is a wave propagating with a potentially infinite wavelength. Not necessary for it to be any light stretching from the beginning of the universe, but also not impossible afaik.
The wave would probably interact weakly with anything making it very hard to detect. And depending on the initial burst it will probably also have it’s energy too spread out to be of any noticeable amplitude.
There’s definite anti-intellectualism, but what you’re describing is the loss of qualified/high innovation industry in the US.
The previous generation of higher education graduates cannot find gainful employment offsetting their student loans, not to mention qualified work at all. There isn’t enough employment or market to make use of that knowledge (there’s also a discussion to be had about the quality of that knowledge, but with the rest of the world managing – let’s set that aside for now), whereas there’s high demand for the trades.
The last few centuries have shown that economic growth is greatly accelerated with higher education, and that access to an educated workforce has been key to post-world-war growth. Meaning it might get rough for the next US generation…
