It matters little whether or not the tax cuts cause economic growth -- what's really important is that they'll increase the percentage of wealth that remains in the hands of free citizens, and decrease the percentage that is grabbed by the socialist government for its own purposes.
Of course, this all assumes that the budget will continue to grow at 3-5% per year, which we do not need.... It is time for REAL budget cuts, to spur REAL economic growth and create REAL long-lasting jobs. If the budget were cut by 1/3, a TRILLION dollars could be returned to the people, or it can be directed to true debt reduction, strenghtening the dollar and securing America's future as an economic super power...
Sadly, this nation is not willing to do what it takes to make us strong... they can only think as far ahead as how to buy their next new car or $500 leather jacket...
