This project led me to propose the Taft Test:

Does your page design improve when you replace every image with William Howard Taft? - This one will come in handy.

It is a big problem, but what would be the ways of solving it? It keeps up with increasing performance in hardware and network. I think that majority of people don't even see it as a problem. As X site loaded in 4 seconds in 2009, it loads in 4 seconds today as well with all of the hardware improvements. 

What about all of the JS front end frameworks? To me they feel heavy and resource intensive, does that hold some water? Maybe I just dealt with crappy projects. 

Considering the response I got from the thread about Windows 10 being bloated, I don't think people are even interested in having high performance on their computers. Like you said, if a page loads in 4 seconds then people think it's fine, even though it might have loaded in 1 second with some better code.

We saw the dramatic effect bloat has on websites in this thread I made. It's when websites started being forced to remove tracking (just tracking, nothing else) scripts to comply with GDPR. Websites started loading 5-10 times quicker, and were half the size.

And yes, all the JS front end frameworks are heavy as hell.

At the end of the day it's a question of cost and in some cases (quite a lot of cases) laziness. Companies are not interested in making high performance code if they can get away with low performing code for a lower development code.
