OK, not rtft but I'm an 'expat' in very rural SW France.
When we moved her 10 years ago, dh thought we could manage on my French and he could get by. We very quickly found that, despite all the research we'd done before, living in a country is a lot different from being on holiday there. We already had 50 copies of birth/marriage/death certs going back to my great grandmother and her inside leg measurement, the staple documents for dealing with French bureaucracy.
It wasn't enough! We started to have private lessons but could only afford an hour a week each. We spent £3k on a 4 week course for me in a private language school including accommodation. After 2 weeks, due to a missing/faulty lightbulb I had a fall on a staircase and sprained both ankles really badly and ended lying across the corner of an L-shaped corridor with my feet on the bottom step. I got up with my stiff upper lip and got on with it. No treatment, no redress. I had to give up the course and go home. Money down the drain.
In such circs, you do not under any circumstances move. You dial 15 (999) and tell them you've fallen. The paramedics are the only people allowed to give an account of your injuries that would have enabled me to get a refund for course fees or medical treatment required.
So, I went to register as looking for work. Pôle Emploi can, and will, pay for you to go on a course that will, hopefully, despite the 10+% unemployment in France help you to get a job. In 2009 this was relatively easy, and on demand, but now that they pay you 400+€/month depending on circumstances to be on the course access is restricted.
I've just finished a course that led to a diploma in payroll/hr management awarded by the French government. I had to do a maths/Excel/French grammar test before getting a place as well as 2 interviews. The qualification was at 2 years post 'A' level standard and it took 6 months, so not for the faint-hearted. However, but there is a growing demand as they are moving gradually to PAYE in 2017 if the laws are passed and they don't burn Hollande in the streets.....
However, it's very far from any and every course being paid for, and it's only available for the few who can show they will or are likely to benefit by paying the cost back to the state in the form of direct/indirect taxation.
We had to stop the lessons as we couldn't afford them, and dh still struggles a bit on the phone. Me less so. I had to put up with comments along the lines of that I was easier to understand on a Friday than on a Monday morning, by someone who insisted that she was tolerant and non-racist. She even did this in front of lecturers, but it back-fired a little - I'm on the list of examiners for obligatory oral exams in English for the centre! It might even be paid!!
However, we've had no access to state funds during our 9 years. Any such demand for the equivalent of income-based JSA in our first 5 years would have been proof that we had insufficient funds to mainttain ourselves. That is how the Freedom of Movement directive is supposed to work. You bring with you enough money not to live on the state unless you work and pay into the system for 5 years and then, and only then, you have the same rights as someone born in the country.
