Once again: Here's the problem:

 As it is presently written there is likely a zero chance that the 3.5 Trillion infrastructure bill will pass the Senate. It could pass the House: "Maybe" but not the Senate.

However, the progressive wing of the Democratic party says unless they have a vote on the 3.5 trillion bill first they will vote against the 1.5 trillion bill in the house which has already been passed by the Senate.

The point here is that the 1.5 Trillion dollar bill needs to be passed by the House because it has already been passed by the Senate and the 3.5 trillion dollar bill is likely too expensive to pass the Senate ever anyway because Republicans will stop it. 

However, if they don't pass the 1.5 trillion dollar bill that already passed the Senate in the House soon it will end Biden as a serious president from now on.

Also, the other thing that has to pass for Biden to be taken seriously is the 250 debt ceiling increase, without which all economies on earth with China first possibly collapsing into something resembling 1929 crash only worse because it will be all countries crashing like a Jenga game.

So, unless the 1.5 Trillion Bill is passed by the house and the debt ceiling is raised nothing else really matters at this point. Because without these two things happening democracy in the U.S. might be over anyway within 5 years.

Unfortunately, the progressives are unrealistic in what they want to accomplish. Someone might want to fly to the moon and eat it like it was green cheese but that isn't happening either because it isn't green cheese to begin with.

People want all kinds of things that are not realistic to get without completely destroying the economy of the nation and possibly the world.

I'm just hoping we can avoid a total meltdown of the world's economies that will be created if we don't raise the debt ceiling. 

This is part of the problem  of spending the money before you raise it to begin with which is what the U.S. government does. If you spend money you don't have before you have the money, maybe you cannot raise the money at all because you spent too much. It's sort of like running up thousands of dollars on your credit card when you don't have a job to begin with. This is why raising the debt ceiling may or may not be survivable for our nation long term because we have just spent too much money already to be solvent in some ways any longer. So, raising money that you likely cannot pay back because it's too high a percentage of your GDP is often fatal for nations down through history which is also one reason who McConnell doesn't want to raise the debt ceiling anymore. But, when you stop spending money is completely arbitrary too. So, why is McConnell doing this now other than to harm Biden?
