"The current youth generation is entering the workforce at a rate of ~150K per month." That's not changing drastically in 7 years. Neither is immigration.
As far as baby boomers, they may be reaching retirement age but actual retirement not for the majority. Especially when we will still be in a recession for the foreseeable future and housing still hasn't finished collapsing.
"Today, many Boomers are feeling far from invincible. The drop in the housing market has removed three trillion dollars in home equity from the pockets of Americans. On average, that is nearly $40,000 in lost equity for each U.S. homeowner. Since Boomers have the highest rates of home ownership as well as the highest home values, they have lost much more than the average. Likewise, the current economic downturn has taken $11 trillion dollars in stock market wealth away. That’s nearly $100,000 in lost assets for every household in the country. And since Boomers are much more likely to have their money tied up in stocks, they have suffered a disproportionately large share of the losses—for many, at the worst possible time.
Unemployment, traditionally the bane of younger and more downscale workers and not something that strongly impacts those at the peak of their careers, has over the second half of 2008 and into 2009 begun to hit the Baby Boom hard. The rate of increase of unemployment nearly doubled for those aged 45-54 in the second half of 2008 versus the first, and increased far faster for those over 55. In past years, most older and longer tenured workers who lost jobs from downsizing could rely on early retirement packages and other benefits from their former employers. Today, those packages are going away as companies seek to cut headcount without incurring substantial severance charges.
Time is not on their side
Assuming a retirement age of 66, the oldest Boomers have only three years left to recoup lost money they took decades to save. The collapsing stock and real estate markets of 2008 alone wiped out four years of gains in the net worth of Americans, and 2009 has taken more. The youngest cohorts of the Baby Boom may still have time to recover, assuming a substantial long-term upswing in the economy, which is by no means guaranteed, but for the oldest Boomers, time may have run out.
Can the Baby Boom afford to retire?
While some can, the majority will struggle and have to make substantial compromises to the plans they once had. Some smaller, but still significant share, will simply have to continue to work in whatever jobs they can find for as long as they can, or else take very large cuts to their standard of living. Those fortunate enough to have sufficient insurance coverage will be able to weather most of the healthcare issues they may face, while those without coverage will see their nest eggs quickly diminish. Many will end up relying on Medicaid and other government programs."
http://blog.nielsen.com/nielsenwire/featured-insights/can-the-baby-boomers-retire/I don't know what rainbows and sunshine world those retirement stats in your post come from but it's definitely not the real world. Perhaps when the majority of boomers begin to die off, maybe.
This recession/working class depression will certainly speed that up.
Still no stats on the culling of the 99ers.
