Ranger: You've got to be a bit younger than I am... you might change your mind when you get closer to retirement
(I am reminded about the story of a young adult coming home telling the old man about the new job they just got and how much it pays.. the old man says, 'fine, but does it have a pension?')
A couple of things wrong w/ your analysis..
First, 10.99% is WAY too high a return. Don't know if you subscribe to the WSJ, but in ytdy's Feb 9 edition, personal section, first page, there was a story SS and about long term returns (this in a publication dedicated to the securities industry). The numbers they (Siegel included) used for long term returns was 6% for stocks, 3% for bonds (after inflation).
Whether this is achievable in the next decades (remember the 70's??) with the huge budget deficit, low dividend rates and continued high stock valuations, high bond prices (low yields), and increased competition from overseas for economic and investment opportunities (remember WWII left the U.S. with little international competition for a couple of decades), is the question. I'm not placing any bets that we'll be seeing dependable 6% returns for quite some time (at least not in the U.S. .. best investment I have going now is a foreign fund.. would we be allowed to invest our private a/c's overseas?? I would guess not.).
But if you're 20 you have time to wait it out. If you're 52 (like my husband), or 45 (like me), you don't have as much time so the long run averages don't mean as much.
Second, 50 years ago you could get one heck of a house around these parts for $25,000. These days $250,000 doesn't even get you a starter house. Your nest egg may sound big, but if you don't factor in inflation (the worst tax of them all), you're going to face a rude awakening.
Third, an 8% w/drawal rate is WAY too high if you don't want to outlive your nest egg.. 5-6% is better, and you'll probably have to adjust down if the market has a bad year.. Personally, I would use 3 - 4.5% (but I plan on living into my 90's if my relatives are any clue..)..
Which brings us to the real benefits of SS: You won't outlive it and it increases w/ COLA each year. It's a great SUPPLEMENT to the money you have set aside on your own for retirement.
But really, IMHO, the whole debate has been brought to the forefront because of the huge twin budget and trade deficits. Something's gotta give and you don't want that to be a dollar/currency crisis (although our ass is a bit saved because the dollar is effectively a world currency.. although that could change too.. like it did for Britian). So, to get our country's fiscal house in order and, since..
1. tax increases are off the table, and
2. there's only so much that can be cut from discretionary spending (note that the "R"'s control both houses of Congress so we'll see how fiscally prudent they can be.. and before you paint me any color, you should know I was a PCO for the Republican party 15 yrs ago), plus,
3. we've got a war to pay for, and
4. we can't default on our gov't bonds (THAT would be UGLY) so we still have to pay the interest on the federal debt (the interest rates are now low, but watch out if they start really climbing.. up goes the budget deficit and we'll be in even deeper doodoo),
5. the only thing of significance left is entitlements, i.e. Social Security and Medicare/Medicaid. And since the President just increased the government obligations under Medicare/Medicaid w/ the new drug cards (that's in the news lately 'cause the cost of that program is looking to be HUGE), that leaves Social Security.
But really, I don't think they're going to institute the private accounts because there's not enough support for it among Republicans because SS is a very popular program.
What we really need to do is to get the budget deficit and trade deficits under control.. how we go about doing that will be most interesting to watch.. either we, as a nation, do it proactively, or it will be forced upon us (not a good option)
