Get off the roller coaster: Oregon needs a budgetary reserve
Oregon is also among the states most in need of such a reserve, because the lack of a sales tax creates heavy reliance on the state income tax, the most volatile of revenue sources...
...Throughout the long expansion of the 1990s, income tax revenues grew steadily, allowing the state's general fund to more than double. When the economy soured in 2001, jobs were lost and the growth in income tax revenue came to an abrupt halt...

And perhaps if a crack addict kept a "backup stash" he would not go through withdrawals when he ran out of drugs...
The argument for a "rainy day fund" is one of the most ridiculous things I have ever heard. (Topped only be the assertion that liberals on on our side in the war on terror) The one thing that government does very well is spend money. They can't get enough. If the voters say no more income tax then they will raise the cigarette tax, the wine tax, property taxes, increase fees and assessments, etc. You get the idea. Government is in constant budget crisis. They will never say enough. If they were to establish a "rainy day fund" this biennium the [fill in the blank] department would insist that it was needed to "provide current levels of service" the very next budget cycle.
I don't want government to hold on to people's money that it isn't currently spending on behalf of the people. Government has some very important functions that need to be paid for but we should not be sending them money to hold on to when they are not using it to provide necessary services. When taking your car to the mechanic you pay for the work that is done on your car for that instance. You don't give them a deposit for future work. The mechanic could argue that "maybe you won't have the money" the next time you need to take your car in but I am sure that you would rather leave it in your own bank account than let the autoshop keep it for you. Especially if the autoshop employs a "diversity coordinator."
