In yesterday's presidential debate on CNN, Ted Cruz floated the idea of allowing young workers to set aside part of their FICA taxes to an individual retirement account.
Now let's look at the basics of Social Security as it stands today: an early retiree who works for 10 years, the minimum to be eligible for retirement benefits, earning a an arbitrary wage of $75,000 a year for 10 years, can expect monthly social security benefits of about 12k/year, give or take a few thousands, when he or she reaches normal retirement age. For more information on this, refer to
RootOfGood's deliciously thorough explanation of SS calculations for early retirees.
Now I couldn't find Cruz's exact proposal of what "a portion of their tax payments" would actually look like, so let's make the bold assumption that one could disregard the need for paying current retirees' benefits, and assume such a plan would allow us to keep all of SS tax in 401(k) clone with even more stringent early withdrawal rules. Recall that SS tax is in fact 12.4% of one's wages, except half of it is completely hidden from view and paid by the employer. Let's also ignore medicare for simplicity. Given the additional $9,300 a year that you are now free to invest any way you like, are you confident that you could beat the government's guaranteed $12k/year annuity?
I think I could. Assuming a 7% return over 35 years on $93,000 (assume no investment in the working years for simplicity), I would be looking at a nest egg of over $900,000. Assuming a more conservative 5% return, it's still almost $500,000. The astute reader will recognize that I have waived away concerns such as inflation, world wars, labor relations, choosing instead to use today's dollar in all my back-of-the-napkin calculations. Even I get to live to 100 years, it still beats the SS annuity.
As much as it would benefit people like us, it would have disastrous social consequences. Average and sub-average Joes, already incapable of managing their 401(k)s, would riot as they enter their sixties without a pot to piss in after decades of mismanagement, predatory advisors taking away their earnings, etc.
