I have no problem with reasonable corporate taxes. IIRC, there is no original intent type constitutional argument about taxes by corporations. There is a problem with personal income taxes from the same perspective. I am all for slashing spending, but if we are hitting only the taxation side of things, my vote is for tariffs and excises to replace the personal income tax.
Tariffs and excises would not come even close to funding a government that has the military committeement this nation has.
