I contruibute to my 403b rather than paying social security. I think its a great idea. Ive had it since day one of residency so I dont miss the money. Its taken out pre-tax (lowers your taxable imcome). Its put into an accont that you can monitior. We have to option to take the money out once we finish our residency or roll it over into another type of savings plan. Our employer invests it for us but they also provided a portfolio of other more aggressive investments where we can move it if we feel daring. I figure I will leave with at least 10k that i will use to jump start my new life. Im THRILLED with it. I say to heck with social security this is what retirement savings should be, i hope to never pay another dime into SSI. If you have the oportunity to do it, yes, you may pay a little more than you would if you just paid social security, but trust me you wont miss the money, you will have to opportunity to invest the money and make more interest if you choose, you will see your money in an account and know where its going, and social security prob wont be there for you anyway..its win win.
