The problem with that is that plastic is cheap as hell and not recycling helps a lot with that price.

You need to make everything 200-300% more expensive for anything to be cost competitive and even that would not mean much.

Not exactly prevention, but is a good thing to do.

So then it is the normal peoples fault. Willful ignorance might not be the best defence for them, nor should it be.

Do you believe everything that they tell you?

Could it be that the other side also doesn't understand them, which is why it always comes down to exact opposites, instead of the more real, slightly different approaches to the same problem?

If this is true, then a foreign military intervention is needed or a civil war.

Unless Hungary, like every country is at least half full of the oppressive fascist types, where most people believe that voting 3rd party is throwing away your vote, so you get the classic 2 party system of interchanging power between 2 people for decades.

Which one is more likely?

To be fair, it is the normal ordinary people who voted for them, unless you imply fraud and a dictatorship, for which the EU probably have some prevention process or oversight.
