Oh, I don't disagree that the government will eventually try to do this. I suppose I should clarify by saying that this author seems to be using small nuggets of a truthful premise--I just disagree that there's much the average person can do about it.
You can invest in gold today within an IRA. You can also put your money in foreign investments. As long as you're invested in an "IRA" however, I don't see how you'll be able to shelter any potential earnings.
If someone is truly fearful they'll lose everything they have to these raving Socialists, they should take every trackable investment today and cash out, paying whatever taxes and penalties that will also come. Then, they should invest in gold, or look into tax shelters outside the United States. Even that's becoming harder to do, as the IRS and other agencies are getting their hands on once-confidential accounts, most likely in the name of preventing terrorism and other national security claims.
I believe you are correct. There will be nothing the average person can do about it. Unfortunately.
