Ha-Joon Chang said this quote

The issue of false consciousness is a genuinely difficult problem that has no definite solution. We should not approve of an unequal and brutal society because surveys show that people are happy. But who has the right to tell those oppressed women or starving landless peasants that they shouldn’t be happy, if they think they are? Does anyone have the right to make those people feel miserable by telling them the ‘truth’? There are no easy answers to these questions, but they definitely tell us that we cannot rely on ‘subjective’ happiness surveys to decide how well people are doing.

Above a certain level of income, the relative value of material consumption vis-a-vis leisure time is diminished, so earning a higher income at the cost of working longer hours may reduce the quality of your life. More importantly, the fact that the citizens of a country work longer than others in comparable countries does not necessarily mean that they like working longer hours. They may be compelled to work long hours, even if they actually want to take longer holidays.

Recognizing that the boundaries of the market are ambiguous and cannot be determined in an objective way lets us realize that economics is not a science like physics or chemistry, but a political exercise... If the boundaries of what you are studying cannot be scientifically determined, what you are doing is not a science.

~ Ha-Joon Chang

Economics is a political argument. It is not – and can never be – a science; there are no objective truths in economics that can be established independently of political, and frequently moral, judgements. Therefore, when faced with an economic argument, you must ask the age-old question ‘Cui bono?’ (Who benefits?), first made famous by the Roman statesman and orator Marcus Tullius Cicero.
