The gap should be linked to rising poverty to be ciritical or very important. However, lower incomes would mean that there are more consumers not able to afford products and services. So either they don't buy, subscribe or rent OR they will take a loan. I don't have to remind us about the consequences of a bursting bubble. I don't propose socialism, but employees should be able to earn enough money to feed a family. It's strange if a business pays less to its employees and hopes to have a higher revenue even if other businesses following the business's example.
