Then you will end up getting a small flat in Sintra, Vila-Franca, Seixal, Cacias, or whatever up to 30 - 60 km from Lisbon and enjoy 1 h commute every single day, both ways.
But you can actually get paid more than that in IT positions, no problem (after-tax salary)
Nowadays the only people I am aware are still getting as much, are senior of my age and older, friends that are self employed, or those that only get half of the salary in official ways (yes undeclared payments are still daily business).
So yeah, while being away for 18 years might not make me have a daily picture, it is not as I don't come regularly back home.
But I'm not disagreeing with you, the salary ceiling is low, I was just noting that it wasn't as low as 1k/1.5k (yeah, 2k/2.5k is more like it, the taxes don't help neither)
