Yes. Just like the ACA didn’t end up looking like what Obama and Dems idealized. It will always be an evolution. Our system is deliberately designed to prevent broad, sweeping change in short amounts of time and force all parties to compromise.
I'd compare the healthcare issue to getting the Civil Rights Act passed in 1964. LBJ was helpful in overcoming the filibuster in the Senate, but it still happened at the cost of putting real teeth in the legislation. It was a compromise. From what I read, the teeth followed in succeeding years. (Also, it passed with a much less dysfunctional Congress--i.e., Republican Party with current party allegiances--than we have now.)
Putting my ignorance on display--Apparently, previous attempts at passing civil rights legislation were stymied by filibusters raising the question: why not get rid of the filibuster? The option to change Senate rules to disallow filibusters has always been there. I think it only requires getting the rule change to the floor and then a simple majority vote. In that sense the constitution allows faster change, but the senators (not the constitutionally mandated system) are always against it. I'd guess their reluctance lies in knowing that one day the majority will become the minority.
I also suspect the real rub is in getting the rule change to the floor, just as today McConnell prevents legislation passed by the House from ever reaching the Senate floor. Again, that is part of the Senate rules, and it apparently puts tremendous power in the hands of very few people. These people might be motivated to retain their power by not doing anything to rock the boat.
Who becomes majority leader? The senator best at retaining political power.
Bottom line--It seems to me that the inaction of the Senate [on civil rights was]
is largely based on the desire to retain power. Keep the filibuster for when you are not the majority, and as majority leader don't rock the boat (go against your party's majority). The R's obsequious loyalty to Trump is based on this principle. It is not the system but the desire for power that slows change.
Odd. The desire for power keeps people from using that power except to maintain power.
I would be pleased if anyone who knows more/better can remove my weasel words or clarify/correct what I've said. Maybe they would just add more weasel words. lol
Disclaimer--I see blaming the system as a way of letting people avoid responsibility. In reality it might be a glass half full/empty sort of thing. Do you want to emphasize taking responsibility or not?
