You clearly have strong points of view on the subject, but did you read my comment? France's physical borders with all neighbouring countries except Switzerland are open. You just drive, or walk, or ski across. The Italian one is notionally open but police pass in the trains and the police presence near the border can be noticeable. The Swiss one is notionally controlled but tens of thousands of cars pass every day and hardly any are stopped. A brown friend skiing out of a French resort wasn't aware of crossing the border, but still spent his whole day in a Swiss border post.

Nowhere do I, or would I, try to absolve France or any other country of its responsibilities. If you're in France with no legal basis, you can work. You can sign a regular work contract. Moreover, a work contract or the promise of one, will (at least in theory I've never tried it) let you get papers to stay. The instructions are [here](https://www.legalplace.fr/guides/promesse-embauche-sans-papi...). If you apply for asylum, you cannot work for 6 months, but you will receive an allowance during this time. Instructions [here](https://www.service-public.fr/particuliers/vosdroits/F2741). France has at various times taken in "lots" of refugies. Most recently returning colonists from Algeria, but also Spanish, Portugese, Russian and Armenian, as well as "poor" immigrants from a string of places. France, unlike some of it's neighbours, operates a "droit du sol" citizenship policy. Immigrants and/or their children can become French.
