Why not eliminate corporate/businesses taxes for 1 - 2 years to see how it would affect the economy?

In conjunction with eliminating taxes, federal spending has to mitigated severely. I vehemently believe that reducing taxes on corporations and business will spurt growth. If they feel uncertain at the end of the year they can just lay off employees (as usual). If productivity and employment increases in that period then it will prove eliminating taxes will spur employment, growth and recovery. I think medicare, medicaid, s.s. payments, unemployment payments, military spending should be mitigated. Discretionary spending should be eliminated except for subsidizing education. I do support clean energy but we can't afford it now and tax the heck out of people to pay for it now, It can be accelerated later. Tax revenues will need to rise later, meaning more taxes to pay for the deficit and investment but the economy is too weak at this point. I also think bloated salaries for the most powerful politicians including various benefits should be eliminated. They don't need them, many are generally very wealthy and could survive a year if the rest of the nation can.
