Earned income tax seems counterproductive to attracting young, productive people, which Oregon seems to need, badly. California and New York are counterexample

Earned income tax seems counterproductive to attracting young, productive people, which Oregon seems to need, badly. California and New York are counterexamples, but California and New York have unique features that offset the downsides of paying earned income tax. I just like not having to file a personal state tax return, the federal one is enough work as is.
