Alternatively, the Liberals could fix their spending problem and stop tinkering with the tax code!  Give consumers, investors and businesses some PREDICTABILITY so that they can plan ahead.   Tax rates are already progressive, and there are breaks for investors and businesses to ensure some incentives for risk taking.  There are unintended consequences with making the tax system too progressive or punitive to risk takers and successful hard workers, just as there would be by taking an extreme libertarian approach.
