>There is no such thing as "shortage" of anything. Just pay more, and you'll get it. ... eventually. Some things take time. If there is a shortage of babies, you need to wait nine months to get more of them, regardless of how much you pay (!). If there are only 1000 doses of a life-saving drug and there are 2000 patients that need it TODAY or they will die, no amount of money can make new doses quickly enough. Labor markets mostly work the way you are describing, but sometimes (especially in cases where training can take a long time, like, say, for doctors), simply offering more money isn't enough of a solution to meet short-term needs.
