When did we become a country when it has been decided you have too much, you don't deserve what you earned
When did contributing 5% of the personal income above $200K to the running of a civilized society become too burdensome and greedy? You certainly deserve most of that money, but to say that 1-2% of your total income is too big a price to pay is pretty selfish and counter-productive.
I see your confusion. The tax proposed does not replace the federal income tax, or the state sales tax, or proper tax, or vehicle tax, or gas tax, or any of the myriad other taxes that Washington residents already pay. It is in addition to.
So the most productive Washington State residents are not being asked to pay '"1-2% of total income". They are being asked to pay that much *on top of* the already significant taxes they are already paying.
Perhaps with that context, you'll understand why fighting any additional taxes is a necessary and honorable thing to do. I am a Washington State resident who will not be taxed under this proposal, but I will still vote against it. I moved to Washington State in part because Oregon recently increased taxes on its most productive citizens.
