[net.politics] Calculation of Social Security benefits vs payments

orb@whuxl.UUCP (SEVENER) (11/13/85)

Opponents of the Social Security system like David Olson
apparently have trouble understanding the power of compound
interest.  Although the Social Security Trust Fund is not
actually run by putting current payments into an interest-bearing
fund, this is a reasonable way to properly consider the
relation between payments and benefits: what would people's
payments into Social Security be worth when they retire
if they had been able to collect interest for all that time?
When considered in this light, Dave Olson's comment:

The relation of 3 to 1 between payments during one's working life
and benefits upon retirement is hardly unreasonable when one
calculates the effects of compound interest.
 
To demonstrate this, let us suppose that we take $100, and
provide an annual interest rate of 5% on that money.  Here is
what that payment would be worth after various time intervals:
       
           20 years    $265.18
           30 years    $431.88
           40 years    $703.42
 
In other words, after 40 years this initial $100 has increased
7 times in value.  After about 25 years it has tripled in value.
If the average working lifespan is 25 years or over a ratio
of payments to benefits of 3 to 1 is therefore perfectly reasonable.
I am not sure of either the average working lifespan before
retirement nor the minimum number of quarters which must be
worked before one can collect Social Security.  I think I
remember my mother (who works for Social Security) saying that
you have to work at least 11 years to collect any Social Security.
This is less than the 25 years at which a 3 to 1 benefits/payments
ratio would take place.  On the other hand, it seems quite likely
to me that the typical working lifespan is much more than 25 years
therefore the amount actually paid in is greater.

Just one more small point, Sevener.  You're calculations
concerning how much someone would get after 25 or 40
years of investing are all very nice, but, they do not
mean a thing as far as SS is concerned.  The SS funds
are NOT invested.  Olsen is right, it is a gigantic
ponzi scheme.

Ah, T.C. is such a careful reader:

1)I was *very careful* to point out that in fact the Social Security
Trust Fund is *not* actually invested.  Please reread the article.
While some people may have trouble understanding this point such
investment is not actually needed given the law of large numbers and
demographic trends.  Banks do not back up *all* of their loans
with actual deposits or assets: the law of large numbers enables
them to predict fairly well the flow of demand for funds and
deposits for funds under normal circumstances.  It is logical that
private insurance companies work under the same dependencies on
statistical averages which can be quite confidently predicted for
large numbers.  The typical atuo insurance policy may cost several
hundred dollars per year, yet it insures protection against
medical damages and physical damages in the thousands of dollars.
*IF* every owner of an auto insurance policy were to wreck their
car there is *no way* that the several hundred dollar insurance
policy would pay the thousands of dollars in damages: the insurance
company would go broke and then all those people would never 
collect their insurance claims.  However this is *extremely*
unlikely to happen.  Insurance companies base their prices upon
projections of the average number of car accidents and damage claims.
Those projections are quite accurate- when they get out of line with
new claims they are adjusted accordingly.
So with Social Security: demographic trends for various segments
of the population are quite stable and slow to change. So,as
Jeff Myers excellent article pointed out, the Social Security
system as a whole is in good shape according to demographic
projections.(always barring Nuclear War which would ruin everything!)
 
2)my point that people do pay in enough money to earn the
benefits they eventually receive refutes the argument that it
is so terrible that "people get 3 times what they pay into Social
Security" and that therefore Social Security is simply a gigantic
giveaway program.  The expenses and receipts  of Social Security
are carefully calculated to insure that Social Security stays
solvent and that it is *not* simply a huge giveaway program.

	Which leads us to an overwhelming question... WHY aren't they 
invested??? The Grace Commission pointed out that huge sums of money
(not just SS money) are left sitting around in vaults when they could
be earning huge sums of interest. 
	Here's another thought. My father suggested once that we could
take a good chunk out of the deficit if social security payments were
taxable as income. This wouldn't hurt people who depended on social 
security as their sole source of income, but the government could get
a lot of money back from SS recipients who have income from a lot of 
other sources (investments, etc.)
