Shame there aren't billions in real estate profits that could be used to attract workers with higher wages.
There isn't a labour shortage, there are more people working than ever, there is a demand shortage - the same demand that is saying the supply is the problem.
If you want to get workers you have to pay them competitively (in relation to what other companies are offering). I work in an office but if someone offers me twice the salary I would go in construction.
Saying there is a shortage of labour is like going to the store full of bread, demanding to buy the bread at 10% the asking price & when they won't sell it to you at that price complain there is a huge bread shortage ... as you stand in the middle of a huge stock of bread (and with enough money in your pocket to easily afford the asking price).
It's just propaganda to not pay workers more & keep profits up. There is no labour shortage.
