It’s tough to finance any project in this economy. Financing one that costs tens of millions of dollars more than necessary is nearly impossible. There’s a message there for the developers of Plymouth Rock Studios, whose bid to turn a golf course into Hollywood East recently suffered what might be a fatal setback when funding for the deal fell through.

The Plymouth project was to be built using a project labor agreement. PLAs require that all labor for a project come from union hiring halls, effectively locking out the open shop workers who make up 80 percent of the Massachusetts construction work force, according to unionstats.com.
