France has very low developer salaries. While 50K is towards the bottom of the barrel with his experience, it's definitely not uncommon either.

50k€ = 75k€ total cost for the employer, and it used to mean 100k$ before the devaluation of the euro. But on this spreadsheet, he wrote 52k TCO, to that’s 35k gross or 26k€ net, ie 2200 per month, it’s very low for an entrepreneur.

I personally can’t find developers for 40 (junior) - 65k€ (decently senior), so, even though recruiters tell me I’m offering 8-10k too much, the actual market may be much, much higher.

I moved to France in May this year, remote dev jobs for mid-senior were starting at 85k euros base.

Which compared to international companies hiring remotely, was very very low.

Which language?

I used to make $28k/year pre-tax as a junior dev (java+frontend, quit job 2 years ago), so your recruiters aren't that wrong.

In his AMA he wrote that that's what he earns before income tax. In French parlance this means after all employer and employee social deductions.
