We've actually had this welfare for 70 years, and the harm was supposed to come any minute now for all this time. Ultimately, its demise is likely going to come from the propaganda against it rather from it actually being a problem.
Who says you haven't seen harm? You're erecting a straw-man.
Also, you have to factor in that when the coffers are empty, France may be more willing to sell weapons abroad... So maybe it's not France that sees that harm.
Ok, is there some French Defamation League, downvote-brigade choosing to censor realities it dislikes, rather than respond?
I note I have down-voted responses to replies that do not have further responses. Hence, from my point of view, it seems when the argument got difficult, down-voting was resorted to..
note: this comment was also down-voted within 5 minutes, again without comment. Those who never comment, never run the risk of malicious down-votes.
