Great, i don'trust the government with my pension retirement. Put all my life savings(that i already paid taxes on) on an investment portfolio. Now the government wants a cut on my unrealized gains as well. Do you realize each time the money changes hands it gets taxed? Do you trust the gov to be as effective and as efficent with that money att all?
