Rich get rich and poor get poorer and somehow thats good?

Is just me or is the debate around tax cuts for the wealthy and increasing minimum wage getting a little crazy?  Somehow many conservative politicians are trying to convince us that if wealthy people get even wealthier it will be good for the economy. At the same time they are trying to keep minimum wage as low as possible with the argument that if poor people get wealthier it will be bad for the economy.
