“I’m in a worse situation than you are, so you aren’t allowed to complain!”

I hate when people conflate:

• Western, Eastern - Western and Eastern Europe, backtracking to the Roman vs. Orthodox schism, and then back to the WRE / ERE split. Not really meaningful outside Europe, except maybe in the Americas; but then it applies equally to former British, French, and Iberian colonies.
• First world, second world, third world - Cold War blocs: USA-aligned, Soviet-aligned, unaligned.
• Developed, in development, undeveloped - that shows where the capital is going to.

So for example. Switzerland is third world (unaligned); Latin America is western (former Iberian colonies); Japan is developed.

On the point. I can certainly relate to socialists in developed countries, complaining about how the bourgeoisie exploits them. It hurts, like being punched on the arm. However this should by no means on the same level as being exploited in developing and undeveloped countries, where the shit is better comparable to being kicked on the stomach.
