Edit: interesting that the person I'm replying to wrote "considered glorified blue collar", which I interpret as status, and that those who are replying to me focus on pay. In the UK a plumber (blue collar) or train driver can make more than a software engineer who is university educated and enjoys a higher status, for instance.
Salaries in tech/software are not that different in UK and France. Perhaps London salaries in hot startups are outliers.
I don't think there is a difference in the way devs/programmers are considered on either side of the channel. The key is not that but rather the company/industry. A tech company will consider them a key resource, an old industrial company maybe not...
