I doubt taxes will go up, except there may be bracket creep. That is, as incomes go up, the tax brackets will stay set at the same place. This will lead to tax increases without anyone actually doing anything.
There could be periodic “tax cuts” either by reducing the rates on the brackets, or by raising the bracket boundaries but keeping the rates the same. Of the two, the former is more impressive. Every once in a while, though, you have to add a new top bracket, like Obama is seeking to do now. Then you can continue to give tax cuts without actually cutting taxes. It’s all a shell game.
So I have to say I don’t think there will be any more tax increases, ever (with the exception of adding new top brackets every decade or two), unless there is a real emergency, like a war or something.
Now, the wage taxes for social security and medicare are another story. But they usually deal with those things by raising the age of eligibility. Still, we could see an increase in those rates. But those rates are capped, so in fact, as inflation occurs, we are actually seeing reductions in those rates as well. What we need is to raise the cap periodically. That doesn’t increase rates. It just increases the amount of income that the tax applies to. Again. No tax increase.
Smoke and mirrors, my friends. Smoke and mirrors.
