Been here 12 years and while I agree with those things (not that I care for IPA or weed), there are HUGE major cons:
-Traffic is quickly becoming worse than all cities in the US and the tunnel nightmare will not solve that (many projections say it will make it worse)
-Local and regional bureaucracy is far worse here than comparable west coast cities
-Massively regressive taxes due to no state income tax (consumption taxes disproportionately levy the burden on poor people, and regional small business taxes/fees/etc are incredibly bureaucratic here in comparison to other areas, though the state laws are favorable)
-NIMBYism is just as bad here as it is in SF, and worse in some areas
-As a result of the above, property values are skyrocketing at rates faster than some areas of SF. My $230k townhome in the middle of a "bad area" bought 4 years ago is worth $500k+. This is ridiculous. There is no reason I should have experienced a 100% ROI windfall for simply accidentally timing the market for housing.
Heroin epidemic is especially bad here, Seattle City Police have been investigated and busted by the US DOJ in the past, high school education has serious redlining going on which encourages private schooling (which is insanely expensive here), and so forth.
I love it in Seattle but it's very much moving the same way SF is, and in many ways, trending much worse.
