I think as long as guests continue to eat the way they do, this is probably true.
EDIT TO ADD:
Here is a quick synopsis. We all know that WDW is seeing record crowds, right?
In addition to the layoffs, you also have to look at the way the workforce has shifted from full time to part time and college program employees. Workers with less personal investment in the company they work for are simply different from employees who are heavily invested. The last relative I had who worked there finally gave up after he could not get scheduled for more than 20 hours a week after routinely working 35. And most of his co-workers followed him out the door (if they didn't beat him to the door). It was no longer worth their while. So the company replaces people with 5-10 years under their belt with college program kids or part time workers. It seems almost obvious to us now that working in a theme park should be a summer job or a short term gig. But believe it or not, it used to be a career.
