The building trades offer great wages after a relatively short time of training and on-the-job experience. What's more, they have a built-in career ladder in the form of the apprenticeship system.
Think of everything that goes into a building, from the outside in, and you'll get a sense of the dozens of specialties that are required. And not just the physical skills of roofing, painting, carpentry, plumbing and so on: building projects need architects, engineers, supervisors and managers also.
While construction is down right now in Washington state, it is expected to grow back slowly over the next seven years—especially in King County, where the population continues to grow and where big public and private projects are common.
Through an apprenticeship, you earn while you learn both on the job and in the classroom. Most, if not all, of the training costs are covered and you're earning a good salary and benefits at the same time. Dozens of occupations in construction (and other industries) have apprenticeship programs.
