"An economy" is not the same as "the" economy. It seems like it should be possible for an economy to be able to contribute to the welfare of society as a whole, and most individuals within that society. However, "the" economy that we have, does not do so. It is a severe indictment of our economy, that pausing all nonessential activity for a few months can be catastrophic to so many people, and for no good reason. As the old joke goes, "we have enough food, it's too bad there isn't enough money to buy it all".
