Summary: As might be expected with the wide swings in the stock market,
some folks will do better than social security and some will do worse.
So do you feel lucky? Do you want to play roulette with the safety net?

Caveat Investor
Introduction
President George W. Bush and the Republican Party are working very hard
to convince the nation that Social Security is broken and moreover that the
only solution is to privatize Social Security.
The driving force for privatizing, is that it will allow individuals to invest their
life savings in the stock market. The theory is that speculating in the stock
market will provide the individual with greater returns than can be obtained
through the current Social Security system.
Below is an investigation of the claims of President George W. Bush's
privatizing plan.
The conclusion is that after including Disability Insurance, Survivors Benefits
and Cost of Living Adjustments, President George W. Bush's privatizing scheme,
is inferior to Social Security for 30%-50% of the population.
1 - Stock Market Returns
The stock market (as measured by the S&P 500) has returned about 7%
annually (compound annual growth rate, CAGR) over the long term.
Social Security Common Sense for more information.
In general the S&P 500 tracks the underlying economy (as measured by GDP)
which grows about 7% annually. See Figure 1.0 (Plot of S&P500 vs GDP
from post-WWII to the present).
Note: Figure 1.0 is derived from the raw data in Table 3.0 (see appendix).

(FIGURE 1.0)
2 - Social Security Interest Rate Projections
The 2004 Social Security OASDI Trustees Report (section V.7, Table V.B2) deals
with interest rate projections. Currently,the average annual nominal interest rate
is about 6.0%.
Projecting forwards, Social Security estimates a future average annual
nominal interest rate of 5.8%.
3 - Benefits: The Stock Market vs. Social Security. Which Pays More?
This is the question everyone wants to know: which pays more.
Figure 2.0, shows the results of a simulation using data from table 4.0
(see appendix) that estimates benefit payments for a typical worker retiring
in 2040 at age 65, for a hypothetical privatized stock market account.
The stock market benefit amounts include a 33% deduction for Disability
Insurance and Survivor Benefits. However, these values do not include a
yearly cost of living adjustment (current Annuities do not have a COLA).
The percentile indicates the number of people in the population below or
above a certain point. For example, the 20% percentile indicates that 20%
of the population are below this number and 80% are above this number.
The lowest 10% of the population would receive about $46792 a year, the
next lowest 10% would receive about $58370 a year, etc.

(FIGURE 2.0)
Table 2.0, compares the stock market results vs. what Social Security would
pay. The COLA column indicates at what age Social Security, with its yearly
cost of living adjustment, overtakes the stock market benefit.
Notice, that the lowest 30% of the population do not even match Social
Security benefits, and by age 74, half the population would not match Social
Security benefits.
Things would be even worse for the stock market, if the simulation didn't include
an extra four years of salary income. Per Social Security rules, benefits are
calculated over a span of the workers best 35 salary years. Any additional
years are not included in the benefits calculations. For a private account however,
all salary is used in calculating benefits. For example, if a worker worked an
extra four years, they would all be included. If these extra years weren't
included the stock market results would be even worse.

Notes:
Percent=Percentile, Principal=How much the worker paid into SS, Total=Principal+MarketGains, TotalAfterTaxes=Total after 33% for disability
insurance and survivors, Benefits=Yearly Benefits Paid
1a) The stock market uses a CAGR of 7.2% less 1% for expenses. And a SD of 16%
1b) Social Security uses a CAGR of 5.8%. And a SD of .86% (expenses already included)
1c) Note: SD (standard deviations): stock market: from table 3. Social Security from historical data
2) Totals (principal + interest) were obtained using by simulating 1,000,000 trials of a 40 year period, from the raw data in Table 4.0.
3) The Social Security benefits are calculated using an estimated AIME formula.
4) Stock market benefits are calculated assuming by that at age 65 the "Total" is used to purchase a Single Life Annuity, with estimated monthly payment of $600 per $100k.
5) Single Life Annuities: Single Life Only, Without Refund: Level payments are received for the annuitant?s lifetime and cease upon the annuitant?s death.
Conclusion
President George W. Bush and the Republican Party are using "scare tactics" to
frighten the American people into believing Social Security is in crisis.
They are also making exaggerated claims as to the benefits of privatizing Social
Security, while at the same time down-playing the significant risks involved.
After including Disability Insurance, Survivors Benefits and Cost of Living
Adjustments, 30%-50% of workers will do worse with President George W.
Bush's draconian privatizing scheme when compared with traditional Social
Security benefits.
The stock market, like a roulette wheel, is a zero-sum game. Someone
wins someone loses. President George W. Bush and the republican party
shouldn't be playing roulette with the security of the American people.
