Rodricks: Baltimore Urban League offers a train to the middle class

Last year, during Mike Rosenbaum’s brief campaign for governor, the tech entrepreneur identified four career paths offering wages that could significantly improve the life trajectories of thousands of struggling Marylanders — technology, health care, skilled trades and manufacturing. Drawing on the big data he uses in his businesses, Rosenbaum found that those fields have the most openings and offer the kind of salaries (at least $60,000 a year) needed to keep pace with the cost of living in one of the wealthiest states in the nation. With training in those fields offered on a large scale, thousands of people could have better-paying jobs relatively quickly.
