Penelope is correct when she implies worker loyalty is a reflection of ones ability to identify with the company mission and values. The problem is, nobody feels personally tied to company values anymore. There's little sense of the work being appreciated or valued by people higher up who should care. And..basically that is the real root of the problem – the people higher up don't care. They have the extra time, comfort, priviledge, capital and intelligence to foster a better environment but, they simply won't. In my work lifetime, I've seen employees, highly regarded one day and, then escorted to the door with security on side the next. I've seen managers cut jobs using the 'last one in, first one out' principle. I've seen all kinds of logic tied justifying the departure of people. It all amounts to the same conclusion – people are expendable. The modern job force teaches me that jobs are increasingly disposable, like our cars, fast food, homes, clothes, cel phones and computers.
The bottom line is this – employers will not increase employee loyalty until they change the perception about jobs and personal stake in their organizations. Until that happens, the 'job' of the modern worker will be to work hard with the radar up and, the walking shoes ready to be set in motion.

The question is basically once I have taken care of my lower order needs (per Maslow)do I like and have respect for that part of me that is viewed through the lens of my job/employer. If not, do I have the guts and resources to change what I do not like.
I would love to save the world, but I feel too old, beaten, scared, and responsible (kids, kids, kids) to leave my relatively secure but unfulfilling job to do so. The typical boomer trap.
Freedom (mostly of the emotional type) is something that I envy younger people, but am honest enough to admit to myself.

Rock on X's, Y's, and M's.
