You can add in the increasing B&O (revenue) taxes, payroll taxes, data center taxes, and the expansion of the extremely high sales taxes to things that effectively make Washington uncompetitive. The cost of doing business has become unreasonably high and is so badly structured that it creates perverse incentives for how you organize business.
And then you have a litany of new business regulation across every sector of the local economy. My recent favorite, which fortunately did not make it out of this session due to heavy lobbying by tech, was requiring data centers to turn-off power during periods of high electricity demand. It's insane that this is even being seriously considered.
Oregon is also a mess but it has always been a mess.
Texas isn't the only alternative. Turning Washington into California with worse weather even makes California relatively attractive.
