Fun fact: Those dudes actually have probably less medals than most western officers in same ranks, just the uniform regulations in DPRK require wearing all medals in their full form instead of ribbons while in dress uniforms.
I expect that with most of them, it's a way to honor the accomplishments of their forebears, which I think is fair enough or at least not the same as "hubris". You can make a left-critique of the rather Confucian ancestor veneration going on here, but that's something else entirely.
It was more of a comment on the meme, not the actual original content of the photo.
If we're taking OPs word on the meme to be true, then it's accepted that most people use clever wordplay to make themselves more competent and important on their resumes than they actually are, putting every tiny accomplishment front and center. Some people even outright lie on their resumes to get ahead.
I'm speaking to the idea that perhaps someone like OP also has skills but is more humble in their approach and is willing to rely on their affability over their less colorful resume. I personally am saddened by it and think we need a world where an ounce of humility is a good thing and being willing to accept our limitations instead of build ourselves up beyond what we really are is good too. The world of resumes refuses any shred of humility and I think the world suffers for it.
I actually agree with your interpretation of the photo itself.
I was struggling to find a job and my friend looked at my resume and was like, dude you need to put more bullshit there, add a bunch of stuff, even if it's fake, no one cares, everyone does it. After so much rejection I was willing to try anything, fortunately a company hired me just around those days. But next time I'll probably have to take his advice...
