My plan is to retire in 5-7 years. I could do that sooner if I went into stock market (and prayed that the mythical 4% per year returns will be sustainable in the future) or became a landlord, but I prefer to play it safe.

Yep - even our prime minister/president doesn't make that much a month, more like half that. I used to know a Polish guy making million Polish zloty/year(so about $300k) but he was the head of the Polish division of a major German insurance company.

Most of my Polish friends working in Poland as programmers(ranging from C++ to Web development) make about ~$2500-3500/month, and that's considered extremely good for where they live(Krakow and Warsaw).

One was a remote job at a SV startup and now I'm making pretty much the same in an in-office job in an international corp. I filled a niche they badly needed to fill (it's not like I'm some unicorn though) hence the unusally high pay.
