I think there are complexities with firing some people... If a manager just walks round firing people with little evidence, all other employees will live in fear of being fired. That isn't good for morale, productivity or creativity.

Instead, the problems of the to-be-fired employee needs to be abundantly clear to everyone nearby, so that when that person is fired, it doesn't have deep social impacts.

Combine that with desiring to fire someone when a replacement is trained up (often many months), and at the end of a big project (sometimes a year), and not just as management is reshuffling... And suddenly a firing takes 1.5 years.
