There isn’t an income tax in Washington.
They just think they are helping the poor.
indeed, minimum wage is a direct redistributive tax, an example of how a tax typically destroys business.
The same couldn’t be said in NYC; they have a state income tax AND a city income tax. These northeastern socialist havens are so dependent on the income tax revenue that when the banks were bailed out, both the governor of NY and the mayor of NYC begged the fed to allow them to pay bonuses to executives. They admitted they may not have earned them, but needed their respective income tax slices to fund their budgets.
The fed likes the idea of increased minimum wages because it drives up the contributions to Medicare and Social Security (and there ain’t no refunds on THOSE withholdings!)
