You are basically saying that all employment is for contractors with fixed start and end dates and that must be extended!
That's not how permanent employment works in many parts of the world, nor is it even desirable.
I have to admit that I'm primarily familiar with the US economy, where nearly all workers are "at will" employees. This means that anyone can be terminated at any time, without a reason being given.
My experience suggests that those permanent employment policies serve to discourage employment. As a US-based employer, I'm often puzzled/confused by some of the practices around the world. (I'm sure the converse is probably true for EU-based employers considering expanding into the US.)
When I say "lifetime employment at a single company," I refer to spending one's entire career at a single firm.
When I say that employment is a voluntary relationship, I mean that the employer cannot compel an employee to accept a job offer, and that an employee cannot compel an employer to extend one.
