sentences:  A CBO study found consumption data not capturing consumption by high-income households as well as it does their incomes, though it found that household consumption numbers are less unequal than household income.Others dispute the importance of consumption, pointing out that if middle and lower incomes are consuming more than they earn, it is because they are saving less or going deeper into debt.Alternatively, higher income persons may be consuming less than their income, saving/investing the balance.
