> So airlines profited around $28 billion in 2019 [1], but none of them thought to sock away money or do anything remotely forward looking or responsible in case of a downturn.
Companies typically do not keep a ton of money around because they're supposed to be distributing profits to the public (i.e., shareholders). Companies that do keep money around, like Apple, are correctly criticized for not re-investing the money into the economy (thus creating jobs and growth) and not returning it to investors (who would, with the dividend, presumably invest the money in another company that had a growth opportunity).
Like it or not, re-using profits is how we have achieved the modern way of life. Keeping money lying around does not spur the economy, which means fewer jobs, fewer products, and a stagnating economy.
