I highly doubt we will resolve supply chain problems, and there are numerous.
1. Supplier countries like China still have stringent COVID-19 restrictions and that influences supply chain a lot.
2. Many manufacturers do not want to bring production to full capacity as there are a lot of unknowns regarding COVID-19 restrictions around the world (for example oil refineries).
3. People have money. They spend less on some stuff, but spend more on household items.
4. There is fundamental shift in economy bcs. COVID. More people work from home, spend less on gas or eating out, but spend more on some other things. Also, a lot of people is on the move. They are moving from certain places to some other parts of the country bcs. they work from home etc. Here in CO it is invasion from NY, IL, TX, CA etc. And mostly those are people who have really good jobs, which hikes up real estate market.
5. Then there is workers shortage bcs. people have other jobs, or really big problem, childcare! My employer has huge problem with that bcs. people are not sure what tomorrow brings when it comes to school or daycare. COVID outbreak in my kids school tooke them out of school 20 days last month. Luckily we both work from home, but even though I am pretty much on my own schedule, I could not do anything as wife has set time when she has to work, so I had to take care of kids. Many people decide that one is just going to take care of kids, while other one works.
etc, etc, etc.
As for Milton&Co, problem with it is that Milton Friedman argued what most academics do: policy that is in the vacuum, forgetting politics. Everyone loves capitalism as long as it serves them, and everyone loves socialism as long as it serves them. Yesterday Congress approved DoD budget that is $28 billion higher than what President asked for. Why? Bcs. DoD budget props local economy, and no one complains about that. It is socialism 101. But, everyone loves it.
