I'm old enough to remember when the WSJ Opinion pages were saying that Obamacare would cost jobs and ruin the economy.
Somehow when Trump took office in 2017, unemployment was at a record low and the stock market was at record highs.
By the way, speaking of things that will hurt GDP: COVID-19 will cost our economy many trillions of dollars. Trump
literally has no plan to safely and effectively reopen the economy. Biden does. It involves mobilizing a large number of contact tracers and using clear guidance to bring back consumer confidence. Read about it here:

We can debate the merits of Biden's plan, but, it seems pretty common-sense to me. There is nothing radical about it. Trump's plan is to just put "Open" signs on all businesses and hope for the best. For Trump to not even have a plan is astonishing.
