As a "live-here forever" destination, Seattle may not be your best bet. As everyone else has pointed out, housing is very expensive to buy, so you might be looking at being a permanent renter...and due to limited space to work with, multi-family units are not being built nearly fast enough to keep up with demand, so rents are also going up. Traffic has been terrible for years and doesn't seem likely to improve any time soon, because so many people have to commute from cheaper areas.
However, Seattle can be a wonderful place for an adventure for a few years, especially if you don't have kids. It's a gorgeous city and has scenery and activities that are unlike any other place in the country. While you probably won't accumulate as fast as living in your current situation, if you are willing to go into a small rental close enough to work that you can use public transit to commute, and get rid of your car (or keep a paid-off old beater for Costco runs), at two high salaries you could still be saving. (I can't speak to your wife's job opportunities, but it might be worth seeing if she can find someone actually employed out here in her field to talk to about what kind of qualifications people typically have. Seattle employers often ask for the moon, but I don't know how often they get it.) So if you are in a position to do it for a few years and then move on, it might be worth making the change!
Note: (You also have to be OK with at least 7 months of grey, cold, rainy weather a year. I loved it, but some people just hate it (my dad, for instance, would never live in Seattle).
