I'm in my early fifties and about half the guys I was coding with 20+ years ago are still coding. Most of the rest are in some sort of management or running their own businesses.
Being employed is all about the value you can deliver. As you gain experience, you usually gain a broad range of skills. Generally, a business only wants to pay for the slice of your experience that directly relates to their business. You skills in 3D math and image processing for example, won't earn a web development company more money. Charging for those skills may make you "overpriced".
The solution, is to always be learning new, profitable skills.
