It is not a technology issue. It is a political, infrastructural and educational issue. Almost all plastic pollution comes fram a handful of countries which do not care about proper garbage collection and recycling.
The west, or for that matter even most third world countries do not cause much plastic pollution at all.

This is naive given that consumption, production, and use of plastics is distributed worldwide, but with a heavy concentration in OECD nations.
You are correct that the issue is political, but pretty much everything else you've said is subjective and shifting blame. The truth is if you use and dispose of plastics you are part of the problem and your country should be working on solutions (the easiest of which is simply to not use plastic).
