Spending 5 minutes on Google shows that the number of construction workers is at all time highs.
It’s just that a hot economy requires even more labour.
My 2 cents, the economy could use a rebalancing by raising wages and reducing profits a bit.
If salaries of construction workers get raised from $40K to $50K, then the number of openings will go down and the remaining workers can focus on the more important work while getting a better wage.
