The only "advantage" these countries have, is that labor is cheaper, so some kinds of labor-intensive activities could in theory be as good as, or even better, than first-world ones (other than climate-related activities such as farming, which naturally benefit from better sun/weather). But the overhead leads to overall worse outcomes.
Corruption does make it worse, but even in a corruption-less environment, the other inefficiencies might still lead to a scenario similar to "pay tax like first world countries but get services like poorest of the poor countries".
Of course, if only all of these privacy-destroying technologies and surveillance-state apparatus could be used to detect corruption, maybe one could have a technological corruption-less dystopia where every figure of power is tracked all the time, as is in a reality show? (In the worst case, we might see some privacy-restoring contraptions emerge from the dynamics of such systems.)
