If a poor single mother working two job has a high tax rate then that is a problem with the tax rate...

And honestly, I'm noticing, in my generation in France, that taking handouts carries less and less social stigma. Whether it is being on minimal income for a few years preparing some competitive exam, taking a long break between two jobs while getting unemployment money, people simply do it. The stigma of private sector work, where especially among qualified workers it include "managing" people, i.e. making them suffer so that they do the company's bidding, exists too.
