My guess is by 2023, Kyrsten Sinema will be a hero as she reminds Republicans that she stood for the filibuster and they should to.

Actually, the 60 vote threshold is one of the main remaining traditions that forces the bipartisanship that Madison felt was critical to keep the country centered.

Madison feared parties. Ideally state representatives represent their constituents and not their party. As such it is hard to see any piece of legislation being universally supported by a majority without significant compromise. So perhaps if we allowed national parties and any national funding of campaigns, we would produce a Congress where compromise would happen long before any bill could get 50 votes.

In the meantime, take comfort that anytime you see anything come down to a strict party vote, that was the worse nightmare the Founding Fathers imagined and hopefully it won't pass.

Lastly, keep in mind, in order for investors to invest in a country and produce the goods, services, and jobs a country depends on they must have some degree of confidence about the future. That confidence comes from knowing a countries policies are not going to swing back and forth every few years. The payback period for major investments is over ten years... companies unable to invest with confidence will need to make their investments produce returns over shorter periods requiring higher prices or shift production to countries with stable policies pertaining to business.
