It keeps you tied to the fedgov in a way that is unacceptable. Money is taken from you at gun point and you are told that if you survive until 67 you may get part of it back doled out in drips and drabs.
And if you are married then only one of the couple gets a full payment, the other gets half.
It is not about the money, it is about the power.
If I had been allowed to invest the 14.4% of my paycheck that they took from me I would be far better off financially.
Heck if I had been allowed to just put it in T-Bills I would be able to have retired a couple of years ago.
Perfect illustration of my point! Thank you for posting that.
