The inequality doesn't come from the creation of wealth so much as the destruction of it. Inflation and rising prices of staple goods (there is some covariance, but the latter seems to be outpacing the former) impact poor people disproportionately hard because staple goods are more or less fixed costs. The marginal utility of an extra dollar is much higher for someone on the poverty line vs. someone who is a multi-millionaire.
