It is a persistent myth that the US does not invest in education. Not only is the dollars per student spent in the US competitive, it exceeds the majority of European nations spending per student by a large margin.
"In 2015, the United States spent approximately $12,800 per student on elementary and secondary education. That is over 35% more than the OECD country average of $9,500. At the post-secondary level, the United States spent approximately $30,000 per student, which was 93% higher than the average of OECD countries ($16,100)."

I see this question only rarely asked. Too many people seem to think that shoveling extra money on X will get you better results almost automatically. No, it won't, corruption and special interests can capture that extra value unless the investor is careful.
Now it is true that underfinancing will get you worse results, but the opposite just does not hold.
Money is going somewhere but most of it isn't into the actual education.
It also means that outside money can lead to successful primaries of otherwise popular legislators, if the legislator doesn't toe the line required. There used to be many Republicans that not only publicly agreed that climate change is a real, human-caused, phenomenon and that also proposed action to solve the problem. After a few legislators got primaried out of their seats, this position is no longer allowed at all in public statements by Republicans, because most legislators are too scared to risk being primaried.
Increasing the House of Representatives by ten fold or more might help.
Getting rid of many of the procedures that prevent votes from happening would probably help too.
And of course, overturning Citizens United...
While you would end up with much more representatives - and in theory more representation - each individual rep would become much less influential. I think expanding the house to be thousands of members large would also make deliberations much more difficult and shallow as a result. I have no idea how parliamentary procedure would work with thousands of interested parties. But I do acknowledge that it is do-able.
That being said, I am in favor of increasing the size of the house, but only by about 100 seats or so. I'd also want term limits in order to facilitate more turnover for district seats. But that's a separate debate.
And by extension lots of issues in Congress arise from laziness / stupidity / corruption / uselesssness of the electorate that put them there. Invest heavily in education and revisit in a few generations.
