This wouldn't have been an issue if we let corporations be money maximizing machines working within the confines of the legal system (and a strong legal system that treats them as such). Instead, we look to corporations for health care, retirement funds, a sense of purpose and belonging. This is the natural outcome.
I don't think another way is possible at least under the current system.
Politicians are able to shove responsibility (like healthcare) on the private sector as a way to address their ineffective programs and social need derived from policy blunders at the govt level. Employer based care can be directly traced to such an instance, for example.
So it seems like the natural state of systems is for politicians to demand the most successful sector (usually private) to intervene, by the way of passing regulations, and thus, given enough time and enough blunders, eventually they will require such sector to own a bunch of competencies they were not really designed for (for example, employers shopping for worker healthcare coverage).
