This is why it's not productive to discuss issues using vague, undefined terms like "the economy."
Wealth inequality is a well defined economic measure and I see no reason why one couldn't use it as a yardstick when evaluating an economy, same as we use the unemployment, inflation, GDP, median household income, and so on. And indeed many economists do use it, and there are many well regarded books and papers that examine wealth distribution.
