A company of 50,000 operating at a loss will eventually fire 50,000 people. If it can turn things around by firing 10,000 - why not?
Further, in a company there might be temporary teams that implement a project and then are laid off. Surely it's better to have these positions than to not hire any people at all.
Even further, life is not static and things change. Not adapting to changes eventually would lead to stagnant and disfunctional situations, where a product would be made more expensive for everyone, just so a some company has the capital to continue hiring 10,000 or so people who are not longer doing any work. But, perhaps more importantly, those 10,000 people are stuck in meaningless positions doing empty "work" for the sake of numbers on some accounting sheet.
And even further futher, if these no longer useful jobs are in manufacturing then continuing them would mean wasting natural resources and polluting the environment.
