The dictionary defines an annuity as “a payment of a fixed sum of money at regular intervals of time or an investment yielding fixed payments during a persons lifetime,” which clearly defines Social Security. So forcing people to purchase a product is nothing new.
What’s the difference is making people pay into Social Security, which is an annuity, and forcing people into purchasing health insurance? I really don’t understand the objection to ensuring everyone is involved in paying for their own health care. The current system of those with health insurance covering the cost for those who don’t doesn’t seem very equitable.
