Who the hell can read 6000 pages in 6 hours and actually understand any of it? Congress should have to come up with and write their own bills. I think it's ridiculous that they can just accept a bill from anyone. Also why do they have such a time limit?
They have the time limit because the government becomes insolvent if a budget isn't decided at the end of the year. Some form of the omnibus bill has to pass - quickly! - to avoid a fiscal crisis, which makes it incredibly easy for lobbyists to sneak shit in there without most of congress even noticing. Most elected officials in congress have significantly less power than committees, the corporate lobbyists who pay for their campaigns, and unelected government bureaucrats who actually implement policy.
