I'm not sure I'm on board with the argument that ALL airlines are a vital industry.
I think what is far more vital are all the small businesses -- 23 million sole proprietorships out of 30 million small businesses -- that really can't afford to just take a few months off from doing business. Hair salons, local restaurants, small stores, daycare, your doctor's office, plumbers, electricians, you name it, basically anything that's not a chain in your local town.
If they implement more restrictions about going out, many of these businesses simply won't make it. An entire town's worth of business could be wiped out because everybody is practicing (good!) social distancing and staying at home.
Small business is just as vital to the vitality and growth of the American economy. Without them, the economy will be in for a long period of recession.
So by all means, throw more money at large corporations who should be required to have their own insurance fund for emergencies like this. But you also better have a plan on how to help the millions of ordinary Americans who are either employed by or rely on a small business in their community. Because if you don't, you'll be seen as just helping another corrupt industry relying on government handouts in order to make their business plan work.
