Yeah Trump's infrastructure project will great for tradesmen while it lasts. Obama had a similar program if you recall, the stimulus. It was also great while it lasted.
10 years (Trumps projected duration) should be sufficient runway to match infrastructure work required with labor. Remember, millions of Boomers, especially in the trades, are headed to retirement over the next decade.
Are you referring to the 'cash for clunkers' boondoggle, or something else?
