government policy is a massive contributor to inflation, it's insane to think otherwise. Paying people not to work, pouring trillions of dollars into the economy, passing massive spending bills, limiting/delaying oil & gas leases, cancelling pipelines, etc is driving prices through the roof. And it would be worse if they had passed the Build Back Better nonsense. The problem with corn isn't that we don't grow enough, it's that we don't allow imports of corn or sugar based ethanol while requiring it's use in fuel so a disproportionate amount of US corn goes to ethanol, which is doing next to nothing to achieve their environmental goals, but we do it anyway. By the way, you can't just open an aluminum mine or smelter overnight nor can you go to 100% EV in a short period of time either.
Now the government is throwing tens billions of dollars at preferred industries to "fix" the supply chain issue. If the government has proven anything, they're really bad at picking winners when it comes to corporate subsidies. What they need to do is get rid of or at least massively reduce the corporate tax and then stay out of it and let the private sector figure out how to allocate capital most efficiently.
