What do you guys think?  Considering that longshoremen make in excess of $120k a year and have great benefits, so it's not a "cheap human labor" vs "expensive automation" issue like Foxxconn et al.

A lot of the jobs they do are not the most difficult to automate, in fact in some countries they've started automate ports quite extensively. Do you think this is feasible in the USA? It's worth noting that the longshoremen unions are aware of the threat of automation and fight against it as one of the core missions, so it is not just a technical issue.
