1000+ page bills that include a lot of stuff is an outcome of the political negotiation needed to get enough votes. A 10 page bill is exactly the kind of law that will face stiff opposition because you have to make major concessions to get votes from both Republicans and the more conservative Democrats who are ideologically closer to Republicans on this issue.
US Democrats did write legislation for the issue and did try to get it passed. They even chose an approach originally developed by conservative representatives to try to appeal to conservatives traditionally opposed to government funded/managed healthcare. It's now known as Obamacare and it passed with the slimmest majority then Congress subsequently tried to repeal, deauthorize, defund, or otherwise destroy it like a 100 times [1].
You could just as easily say that if the majority of citizens actually wanted to fix this problem, they would vote out anyone who voted against a conclusive bill. But doesn't happen because voters actually approve of these politicians anyway. You can spend all your money on publicizing "who voted against this healthcare bill" and accomplish exactly nothing, anyone who cares can easily find out anyway.
But sure, it's always rich people's fault.
