A low-cost state loan to train manufacturing workers is drawing support from business groups that say Connecticut is ill-prepared for an increase in aerospace and other high-tech factory work.

Some economists dismiss the complaint as overblown.

Last week, Gov. Dannel P. Malloy announced a 10-year $711,533 loan at 2 percent interest to help Berlin machining company TOMZ Corp. expand and build a training center at its site.

Malloy says the state is acting to counter a shortage of skilled manufacturing workers.

Massachusetts Institute of Technology professor Paul Osterman says companies report spot shortages of manufacturing workers, but it's not broad-based or pervasive.

Economist Peter Gioia (JOY'-uh) says rising demand for aerospace is stoking state efforts to train more workers.
