Employers might not care in the short term, but in the long term they have to, because the general skill level of the labour market will be significantly diminished.
As long as individual employees are willing to invest in themselves and change employers, this isn't a problem. Employers have effectively off-loaded the cost of career development fully onto employees. This is even more true at the low end of the career/pay/skill spectrum.
Anecdote: I have a friend who manages a large food production plant in middle America. He constantly gripes about being unable to find skilled welders to maintain the giant metal vats used to mix/cook/etc ingredients. But, he's reluctant to start any sort of apprenticeship program because it costs money. He'd rather keep the employee churn and bitch on the internet instead of up-skilling existing employees or creating a training program for new employees.
