Once you realize that trickle-down economics does not work, you will see the excessive tax cuts for the rich as what they are -- a simple upward redistribution of income, rather than a way to make all of us richer, as we were told.

95% of economics is common sense

Since the 1980s, we have given the rich a bigger slice of our pie in the belief that they would create more wealth, making the pie bigger than otherwise possible in the long run. The rich got the bigger slice of the pie all right, but they have actually reduced the pace at which the pie is growing.

95 per cent of economics is common sense – made to look difficult, with the use of jargons and mathematics.

... the human tendency to be seduced by a theory that supposedly explains everything.

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.

I would go one step further and say that the willingness to challenge professional economists - and other experts - should be the foundation of democracy. When you think about it, if all we have to do is to listen to the experts, what is the point of having a democracy at all? Unless we want our societies to be run by a body of self-elected experts, we all have to learn economics and challenge professional economists

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.

In manufacturing, where mechanization and the use of chemical processes are much easier, it is easier to raise productivity than in services. In contrast, by their very nature, many service activities are inherently impervious to productivity increase without diluting the quality of the product.
