I had 3 times the average national net salary, not GDP, which I guess should be even more. But that income wouldn't have allowed me to retire either. It would allow us (me, my wife and a child) to live a comfortable life though.
As a back of the envelope calculation, if you can live with 30% from the income, one should be able to retire in about 7 years.
insurance and healthcare system is a joke. so whenever you got health issue, be prepare to spend butt-load of money.
i have no idea how gdp per capita is so low yet people have so much of money (unreported income, corruption probably)
I make about 25 times the national gdp per capita yet i'm just above average in my country.
