This implies that inequality is bad. I would rather argue that poverty is bad, and it is at an all-time low [1], consistently raising the HDI everywhere technology is introduced. Inequality in itself is only bad with regards to jealousy, which should be addressed through economics education.
Inequality as we see today is bad, regardless of progress on poverty.
Some people today could endanger the lives of those they disagree with, simply by doxxing them. Yet, they'll face little to no opposition in the courts because they're uber-rich. No one should hold the power of life or death on a whim.
Unless you think centralization of power is a good thing, you're wrong. Things can too easily go wrong when the word of one man, however talented and wise, is louder than the voice of millions of people.
