During the time that I ran a liquor business in nearly the highest per capita income zip code in the US, I did a great deal of my business in 1934 series one hundred dollar bills, received from blue hairs of means. These were wealthy, intelligent people who realized that the government was watching them too closely. True, they made those refrigerators full of 1934 hundreds in earlier times, maybe illegally, but they realized what was coming. "What Was Coming" was that our Federal Government would be looking deeper than just illegal activities in the future. They were right, now they are looking at anyone who can feed the welfare trough. I would recommend to our younger people that they ignore the "investment" concept and keep saved cash in mattresses or invest in their own business or property. Except for thieves and politicians, those who invested in mattress money and independent business are the ones who survived the recent emergency.
