Please explain how lack of state income tax has anything to do with this problem or vis versa, how the state income tax revenue would actually contribute to fixing this problem? There are states with state income tax that has the same problem as Washington like California for an example. More taxes does not automatically mean they go into fixing the core of the problem nor does it mean they'd fund the mental health program enough to address most of the problems. Mental health is not a single cause of the homelessness problem that is "infecting" the west coast right now. For an example, medical bills could easily and have bankrupted people without actual mental problems. So, how would funding mental health facilities going to help these people have a home?
