It's a short ending, but, yes, it is symbolic and allegorical. This isn't reality. So, I just want to say again that the treats themselves are irrelevant, as well as other concerns about needs and materialism under pre/post-revolutionary life, but what they could mean in the film is what matters. And the film is very clear that he gains them through the sale of arms, and that he values them as a socio-cultural elevation of status and lifestyle. There's no question there. They are intrinsically tied in the movie both to blood money and capitalist elitism.

So, in my interpretation, his decision to move back to his uncle's garage but with his capitalist treats rings hollow as a sign of real paradigm shift or repentence. He didn't have a change of heart, turn around and sell arms to Hamas. He didn't give away all his shit and completely start over with a new sense of self. He was a struggling working class person with some internalized desire to be an elite, reached some new elevated heights and profits via capitalist war machine, used those profits to have a better luxurious lifestyle, and then realized he did a wrong, so left the job and moved back with his uncle but kept his stuff. That seems significant. Honestly, yeah, if he really realized the extent of what he did he would have probably been disgusted with those items and either discarded or donated them. I've been disgusted with items for less. His keeping of the items is something which is intentionally meaningful or has the capacity to be interpreted with a meaning. Materialism and political pragmatism aside. This was included in the film for some reason, consciously or subconsciously, related to the plot. And I believe, given his previous embrace and comfort under a capitalist form, that these are symbolic of that ideology which he has not yet shed. And, as such, I don't believe he is an honest or apologetic person. I think he continues to carry his capitalistic desires and dreams, as symbolized by his still clinging to the items he gained when his capitalistic desires reached culmination in reality and he could buy pretty much whatever dumb shit he wanted—and he literally bought that very shit with his blood money. Dude is deeply captured by capitalism but also wants to feel like he's on the side of angels by leaving his old job but still keeping his ill-gotten gains. I don't know about you, but I've met shitty rich people like that who did shit fuck to get rich and now volunteer on the Board of some nonprofit or whatever and feel like 'they give back' after robbing everyone. Fuck that.

Outside of the movie, again, yes, all living people should have some decent standards of living. However, I think some people don't deserve to live in a revolutionary society.
