That's a great way to ignore the problems of people not like you.
I'm sure you'll change your story to further illustrate how evil you think these people are, but the reality is they're not evil, and they don't really have other options, regardless of what went down in your world when you were younger.
No matter how many times you say otherwise, people would rather not steal. Fix their circumstances, fix their behavior. If you actually cared about solving the problem, you’d care about helping these people.
But no. For you, this is about petty vindictive retribution. Your inability to empathize with someone not like you creates a cycle of hate that’s self perpetuating, further exacerbating the problem rather than being effective in finding a lasting solution.
You need to get out of your bubble man.
I've got a number of other comments here at this point that cite sources which explain things better than I'll ever be able to, if you're actually curious, I recommend you read those sources (and others, "are people good?" is a fairly well trod area of psychology, and indeed philosophy).
Later on I knew people who stole electronics --not as juveniles any more. It was just easy money for a night's work. They didn't have to put in 40. Didn't have a foreman. They'd brag about how easy it was...
So, I don't believe they have not alternative but this. It may be an "easier" option compared to other options, but it's not their last option. No. People in the Eastern block had less purchasing power than a poor person in the US. They did not have a culture of thievery. One, they were not a consumerist society and two, they would give no quarter to thieves.
