It is better to have too little government involvement in the economy than too much. I'd rather err on the side of economic anarchy than economic central planning.
Geezus, dude. Put down the Communist Manifesto and join capitalist society.
Patents are a rejection of the anarchaic free market capitalism of yesteryear. Why should anyone, from you to Microsoft, have to pay anything to use someone else's ideas? You build a better mouse trap and you should be free to sell it to anyone that wants it without paying out your ass in patent fees to the guy who came up with the original mouse trap.
As long as you have patents you won't have true competition. Congress has the authority to provide certain industries like the pharmaceuticals with select protection, but leave the rest unprotected. That's the other side of Article I, Section 8, Clause 3.
And speaking of Communists, how are you liking Bush's Keynesian deficit spending, massive handouts to old people who didn't bother to buy health insurance and/or save for it and calls for more and more cash to be thrown at Iraq? I'm sure there's a good rational argument for adding much of Iraq to the federal payrolls during a time of budgetary crisis.
