How realistic is construction employment growth of 570,000 workers? It hasnít happened since 1946. Even the peak of the housing bubble generated only one brief year-over-year increase of 500,000 construction workers.
Without any radical changes to immigration policy, we might have capacity for an additional 50,000 construction workers per year for infrastructure projects -- far short of the 570,000 needed under Trumpís infrastructure proposal. Significant growth beyond that would likely require much higher wages and poaching from other industries, creating labor shortages in those industries.
