I agree completely. If people cannot provide for themselves, the state should provide for them. I don't think it makes any sense for employers to be tasked with that, since all that does is provide a huge incentive for employers to discriminate against those who need more (and thus would cost more).

To incentivise performance, employers should pay based on performance. If an employee cannot perform well enough to provide for themselves or their family, the state should help.

None of this requires that employers directly decide pay based on whether you have a family. Requiring that results in the employer discriminating against parents and employees having a reduced incentive to produce.
