claiming that the interstate highway system wouldn't have been built without lcn is the same type of silly logic that would claim there would be no planes without the wright brothers.
Actually that comparison makes no sense.
There would be no interstate highway system without the LCN because in the 1950s there was not a sufficient organized labor force capable of pulling off such a huge undertaking.
As massive as the construction was, it required the lowest skilled labor in all of the construction industry, and it also required local mom and pop contractors to work nationally across 48 states.
Enter the LIUNA (laborers international Union of North America)
who without the LCN would never have functioned as a viable Union. The Buffalo and Cleavland families alone made millions for the union through legal, I'll say it again, LEGAL loans through the pension funds.
It was that organization that made the Interstate highway system possible.
