Fair! Chronologically, at least, Diocletian's time is closer to us, though not technologically or population-wise. And by Diocletian's time, inflation was already out of control. If anything, the political stability that came with Diocletian's reforms actually helped bolster the economy, though it wouldn't last, as soon the center moved to Byzantium, leaving Rome (and Italy) to whither and die over the next century.
