In France its basically like they don't want a tech sector. Employee's rights are skewed so far to the left that Employers are often hamstrung and startup-culture is completely stagnant. Even running a Cafe you can end up paying an employee for a year or two who literally can't or won't show up for work.
In short though, Ireland/UK/Belgium are the highest paying areas for tech in Europe outside of a few select Financial/Banking enclaves in Geneva and Zurich, with the majority of non-FAANG Seniors capping out at €120k or thereabouts without going into the niche areas like SRE or Algo or Cloud Architect.
