So employ someone and train them so they are qualified

That just means the cost to hire includes the cost to train people.

And realistically, training is always a cost, even if people don't acknowledge it. It takes time for experienced people to get up to speed at a new workplace.

If I am the only qualified person and there are 2 jobs that are paying all the money in the world I will work 16 hours a day on both and earn 2x all the money in the world.

I think this comment misunderstands the whole supply/demand curve idea. At a low enough price, there would be an arbitrarily high number of "open positions". The statement "there are 10 open positions but only 8 qualified people" therefor is trivially true and meaningless. If I could pay people $1/hour then I might hire 5 of them full time personal assistants. But people wouldn't work for $1/hour, so in that case do we say that there are 5 open positions but 0 candidates?
