Do we really want businesses to hold onto cash, sitting idle, just in case a once in a century pandemic like this hits your industry particularly hard?
I don't think that makes sense. People talk about 'socialised losses' as if it's the devil's work. I think socialised losses aren't that bad when talking about such unique events. Should companies really be holding on to cash for once in a century events? Imagine a 1950s CEO had been hoarding cash for 70 years. Now imagine how much wealth has been generated, by putting that cash to use, including by paying it out as cash to investors who'll go on to finance new businesses, new jobs, new research etc.
That having been said, while I'm not opposed to socialised losses / bailouts per se, I don't really quite see yet why airlines need bailouts. Their stock valuations rose due to bailouts. Now they drop some due to the crisis. They should be high enough to sell more stock it once bought and raise new capital. In good years you buy the stock back. In bad years you sell stock. What's the problem? Yes investors take losses, it's part of the game. That's why you diversify. If you don't, that's on you.
Not sure how far the US goes, but in the Netherlands all employees have unemployment insurance if they get laid off. And those who don't, get a little over $1k in social security, plus various subsidies on rent, healthcare etc. Companies in trouble can layoff people, and they're taken care of with the insurance premiums paid out in the good years. The company sells off stock and hunkers down. The government offers cheap lines of credit. Good businesses survive, a few bad ones die off. I don't see why a big bailout is necessary.
