I will make it quick.
If the government came out with a program to stimulate meat consumption today, then yes, people would sprint out and buy more steaks but there wouldn't be any more on the shelf and the result would be that prices would go up. Likewise, if after the lockdown ends, the government tries to spend more and more borrowed dollars stimulating artificial demand for products and services that no longer are produced, prices will do exactly as they did at your grocery store. They will go up, because you can't consume what you don't produce.
Would you agree with that?
