Inequality is not a good metric for whether or not things are getting better.
As Thomas Sowell said, “Now the history of the United States in the 20th century shows an incredible increase in prosperity over that century, and it was brought about not because [the poor]’s slice of the pie got bigger — the whole pie got bigger. And so everybody had an increase in prosperity.”
And anyway, "income inequality" actually increases the more your government has subsidies for the poor. The more the poor are subsidized, the less incentive they have to work longer hours, the less they receive in income. It's not a coincidence that income inequality was lowest when countries had no government welfare programs at all.
