Imperfect information is pretty common.Many people who got caught up in variable interest mortgages claimed not to know the interest rates would go up after a few years.Many people have been defrauded in Ponzi schemes.Not too long ago a poor elderly lady was discovered to still be paying $3.00 a month to rent her phone from AT&T, something that was done way back in the 70s and before, when you could not own your own telephone.One recent scam that has surfaced are people calling to help unknowing suspects to sign up for Obama Care and getting payments, which is stolen money.Another is people calling and claiming the person missed jury duty and demanding money to pay off a fine.Do you know anyone that has been defrauded or suffered simply because they did not know what they were doing?
