Why is this little construction crane illegal in New York City? (2016)
This is sort of like how when the waterless urinal was first commercialized, the plumbers union blocked it from getting approved in the general building code.  Eventually a compromised was reached that involves requiring a plumber to draw an water line (unutilized) to every water-less install.<p>Unions for skilled, high-pay jobs in highly regulated industries really extract a lot of questionable value from society.
