Okay, supe. . in a nutshell; our locco 'gubmint' is the problem.
You moan about the transportation mess around here. Do you, for a moment believe that our politicians have the answers? . .. All that they want to do is have giant bridges, trains, mono-rails built in their name.
That is quite different than allowing engineers solve choke-point problems, at say, some intersecting freeways.
These power-hungry, money-grubing dem's want to spend-big for the sake of living large.
An EVEN BIGGER issue, is the (false) premise that the Seattle -meto area is where EVEYONE want to go . . .where EVERYONE wants to be whisked about in a fabiously expensive train. (side note; I hear that as it is now, the amount of money spent keeping the Sounder-train going could have bought an Escalade for each of it's regular commuters . . .and just think how much tax those gas-hogs would add to our economy

)
Seattle is a great place to visit and all, but more and more people are working from home offices, or suburban towns.
This idea that all of the state ought to pay for Seattles uber-expensive projects is just wrong, and poor planing.
