Krugman is part of the problem, CAN NOT be part of any possible solution Learn to Stop Worrying and Love Debt by Paul Krugman NY Times Dec 2020 https://www.nytimes.com/2020/12/03/opinion/biden-republicans-debt.html
Market economics is a proven reality even if politicians and economists would like too obscure the reality They think they are smarter and more capable than free markets. History has not only shown them to be wrong but that they have a seemingly uncanny ability to create problems and then to worsen them through interventionist policies.
The fact that they gave Krugman a Nobel was the end of the modern notion that the award has any credibility remaining.
Remember Krugman is laughing all the way to the bank, which proves he may not be a good economist, but he is a great salesman.
Have you ever heard of the role of public goods and the free loader dilemma lol? Point me to one country that has an effective private infrastructure system.
History shows literally the opposite. Today's conservatives are blinded by abstract principles with no empirical basis. Krugman may get some things wrong but he is right most of the time.
I love the obsession with "credentials"....as if Krugman and others who couldn't have been more wrong haven't made that laughable. I actually thought about getting a Ph.D. in economics when I was younger. But I realized they had an inferiority complex and tried to make it like branch of math or physics. Talk about square pegs and round holes.
