Personally, I'd be fine w/ 100% in the market.
Even after the crashes we have experienced in history, the returns over time are still exponential. It's a no brainer.
What do we get with SS now? 2%?
Awful....
Absolutely correct. What the fear mongers of stock investing tend to forget (or gloss over) is the difference between short term and long term investing and how that plays out in the stock market. Relative to the bigger picture, the working lifetime of an individual is, at best, a MID-term investment longevity. Stock downturns are comparatively short lived to overall stock growth. The people who got hurt were the ones who either panicked and sold while prices were in free fall, or the ones who were forced by circumstances to sell at that time. People who hung on were not hurt nearly as bad, and will eventually recover everything and a healthy dividend besides. People who hung on AND invested while stocks were cheap are going to come out WAY ahead.
The fund is big enough to weather downturns, while the continued input from FICA taxes could take advantage of those downturns, which are assured good gains. Look at the most recent downturn. The DOW was down to around 6500, which was very bad news for the short term. But it's back up over 10K even with recent losses. For money invested while it was down, that's a 50% increase in 18 months. One of my favorite stock, Apple Corp, dropped to around 80, and is now a few pennies under 250. Not quite tripled my money on that move (bought at 92 while it was still going down). Hire a bunch of smart investors to take care of the fund, and SS would be safe for centuries without any need for raising the cap or otherwise increasing the FICA tax. Even with the most all downturns included, the annual increase of the stock market has averaged a bit over 10% over its lifetime. And that is 10% annually that the tax payers do not have to pay for.
Conversely the measly 2% "investment" of SS funds comes from the tax payer, placing one more burden on an outrageously overspent federal budget. Not to mention, by "investing" SS funds in T-bills, it effectively transfers those funds to the general fund, where they can be spent at will on any damned thing uncle Sam feels like. It's how the Clinton administration cooked the books to claim a "balanced" budget. They spent all the SS surplus after converting it to T-bills.
If the basic structure of SS were left as is: a giant pool from which benefits are paid, investing the money in the market would significantly ease the strain on the system The SS surplus fund would double every 7 years WITHOUT additional input. WITH additional input the government could secure payments for the future AND could decrease the tax rate on the people at the same time.
Last point: the SS surplus fund sits at over 2.5 Trillion dollars. Imagine that effect that amount of money could have on business. Corporations sell stock for the purpose of generating revenue for expansion. Expand the markets by 2.5 trillion, money that exists instead of borrowed by the government, and the word "stimulus" would gain real meaning again. Expanding business means new jobs, better paying jobs, development of new ideas from R&D departments, etc. etc. etc. The item of concern here would be having TOO much influence. The law would need to be written so the handlers of the fundd could not invest too much in any one area.
