Lots of assumptions are being made on this thread, and this issue. IF the rule is changed the percentage of pilots reaching 60 and then continuing to fly will probably be fairly small. Many can't even make it to 60 to begin with due to medical issues, etc. Those who have done well financially will elect to stop flying, I would stop flying for a living now if I could afford to.
The idea that older pilots are less skilled is pretty ridiculous. Every older pilot I've ever flown with has taught me something new and generally impressed me with their level of skill. As has already been said, the reaction time, might be a little slower, but the experience more than makes up for that. Besides, how quick do your reactions need to be to fly a transport category jet. It's not like a jet fighter.
About 14 years ago I flew with the former chief pilot of PSA, he was 70 at the time. We did a flight across the States in a Twin Otter. At the time he was a check airman on the Twin Otter for Scenic as well as a designee for their Ford Trimotor. He flew Cessna Caravans to Africa and a load of warbirds for Cinema Air in Carlsbad. Heck of a funny guy and a darn good pilot. Later in the later 90s I worked with Boeing/Flight Safety Boeing in Long Beach. Most of the instructors there were retired airline pilots. The two check airman on the MD-90 were retired AA. They both could fly circles around most pilots. Also there was the 65 year old former Chief pilot of Air Cal, who could also fly circles around most people I know. That's just to name a few of the many talented individuals in Long Beach. While there may be some pilots whose skills deteriote with age to the point that they are unsafe, I haven't seen it. As said previously, they were probably dangerous at a younger age to begin with and just got lucky to survive as long as they did.
The last thing, I'm also furlughed from a major so a change to the retirement age could adversely affect me. Yet I'm still in favor of it, because I tend to think long term, not just short term. As I keep saying, I'll go before 60 or at 60 if I can, but I want the option to continue.
