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.
