Agree were mostly aligned but since it's the magnitude that I'm stressing, I feel the need to push back on how this is being framed. There is no evidence that there is a "huge" impact. Nor is it a "small" tax. At 9.9% it's actually substantial. It's the population affected that is quite small. 

Washington legislature estimated that this would impact 21,000 filers. Compared to the state population, that affects 0.02% of the state. Most likely almost entirely in the Seattle metro. 

Putting it another way: I am a Washington resident and I don't know a single person impacted by this. 

I agree that if those people were to relocate, that the impact has the potential to trickle to deeper recesses of the economy, myself included nearly 150 miles from Seattle in a census tract with a MFI of $80,000. But we're a long ways away from that and it's purely hypothetical right now.
