Could start a rotating door policy. You have to be rehired every period.
If you spend is going up, you're pre-paying more and more tax on profits you haven't earned yet. If your spend is constant, you'll stay the same amount behind. If your spend declines you'll start to catch up, and if it drops to 0 and stays there for ~4 years you'll catch up to where you would have been without the law change...but if you start spending again you have to start pre-paying again.
