Why tax the rich on their income?  Let's force them to spend their wealth instead.
Taxing the rich cannot solve
 our deficit problems, and it will take discretionary spending dollars 
out of the hands of those individuals most likely to spend in the first 
place.  Instead we should compel the wealthiest individuals to increase their discretionary spending, boosting the economy and ultimately creating more GDP for taxation.
Offer
 a future year tax credit for excess consumption in the current year.  
Or create limited current year deductions for luxury spending.  Or tax 
credits for large ticket luxury purchases like private jets.  Or for 
spending invested wealth directly on consumption.  Anything to push well
 off individuals to spend a little more.  You could go so far as basing 
this spending requirement on accumulated wealth instead of current year income.
Compulsory
 consumption would be similar to taxation and stimulus except the 
decision making power remains with the individual (except the decision 
to spend at all).  Unlike taxation, affected individuals would be free 
to choose products and services most beneficial and enjoyable to them.  
And since spending would be driven by choice, stimulus would be applied 
to a diverse array of sectors all at once.
Rational 
wealthy individuals will buy products and services that cater to their 
tastes, which limits the stimulus effect to those businesses.  But in 
turn they will pay employees, invest and create jobs, and buy products 
and services from other businesses.  Top earners for those companies 
would be compelled to spend as well, creating additional spending 
throughout more of the economy.
This is the same effect
 provided by tax cuts or direct credits to individuals, except the 
government does not have to actually pay for it with debt or reduced 
spending.
