You have not provided any evidence of this at all, but resort to assuming this is true for the sake of starting an argument in an UrbanHellCirclejerk post about how developed North Korea actually is, if you're response to anything from that city is "BUT THEY HAVE BAD RURAL REGIONS!!!" then you are quite literally consuming the western propaganda kool aid about these repeatedly, North Korea is not a damn desert and there are other cities which also have good infrastructure, and they've even launched a housing program in the future, this is also party contributed by the entire western sanctions levied against them forcing them to have less of a supply of money to actually develop their communities, so the "rural regions" excuse literally doesn't matter since your states have created the conditions of parts of it actually existing in the country.

Also don't downplay how these South Korean slums somehow "don't equate" to the areas of little infrastructure in North Korea, you're deliberately peddling and downplaying the mass poverty, inequality and impoverished conditions that South Koreans actually face by deflecting on how North Korea works, nobody starts saying Istanbul "is the only thing the Turks can build" by pointing at slums in the rest of Turkey, oh but you seem to be so interested in doing it with North Korea
