What rationale could you use to explain the following statement: " income mobility makes lifelong incomes much less unequal than annual incomes."
a) There will always be an element of the haves, and the have-nots in a market economy.
b) People whose incomes are low over their lifetime skew annual income averages.
c) Because individuals are free to move up and down the income scale, they have the ability to spread annual income inequalities over their lifetime.
d) Annual incomes do not always affect lifelong incomes.
