Whenever there is a new proposal or projection; M4A, expanded Social Security, Medicare’s costs, etc. the projected costs and consequences are based on many assumptions, sometimes assumptions linked to other assumptions.
Merely tweaking assumptions can change something into whatever you want it to be. And frequently the assumptions used prove wrong … because they are assumptions generally conjured up by some individual.
In addition, many times assumptions attempt to predict the behavior of individuals…that is especially risky.
So, before you jump on this or that bandwagon of promises, check out the assumptions used in making those promises.
