Answer:
the income inequality between the salary of company CEOs and the average salary at the company is harmful and unnecessary.
Step-by-step explanation:
Thomas Piketty is classified as an extremely social economist along with Joseph Stiglitz and Paul Krugman. Some confuse them as liberal economists, when they are actually against liberal or neoclassical economies. The three of them are famous for promoting economic fairness and equality. E.g. Piketty opposes extremely high CEO salaries while low level employees earn wages that are dangerously close to the minimum wage. He believes that this type of management practices are unsustainable and damage the economy in the long run.
Personally, I believe that the most important sector of the economy is the middle class and that the larger the middle class, the better.
