Earlier quoted context omitted.
Yes, if you can manage to find even some 40k or 50k/year contract it will put you into about 5% of top earner in population in many central/east european countries. Prices are not as low as you might imagine, but it will give you a very nice life standards. You are not going to be able to afford luxury cars or other luxury items (those costs the same everywhere), but otherwise you would be set.
You will be rich in Eastern Europe but you'll still be considered average/poor in the developed world. Doesn't sound like a huge bargain to me.
The fact that you would not have the same position abroad (i.e. your cash savings are large locally but small if you lived in a rich country) is not a loss of any kind, it's just a fact that has no bearing on daily life.
