"distributed 100 times more unequally" doesn't mean anything, certainly not anything that implies anything about "the worst off". You need to characterize what happens to that specific part of the distribution if you want to estimate the impact.
In particular it is possible to reduce the shares of the top N%, and the bottom N%, increasing the share of the middle, and have many measures of inequality go down.
