They could have put aside money for a rainy day, or kept services at the level that they were so that when things went back to normal, they wouldn't be so stretched.
But this is not how government works.
Since taxes are set at a percentage, it would seem that they should never need to be raised, right? If it costs 1/10th or 1% of GDP to keep roads in repair, when the economy is booming, there may be more roads but that percentage is more dollars in real terms.
But what governments often do, and what Washington has done here, is just spend money on other things, let the roads get bad, and then claim that they aren't getting enough money to keep the roads up to justify raising the road taxes.
It is a simple game of bait-n-switch.
The big money is in getting people to sell future economic growth to resolve a short term artificial pain-- which is what they're trying to do now. Sure the state income tax will be a "tiny tax only on the rich".... but the federal income tax started out that way, and look what it has become.
Washington state has spent money irresponsibly. They should be forced into financial prudence.
Glad to see some entrepreneurs understand enough economics to oppose these kinds of power grabs and bait-n-switch tactics.
