OMG, not long ago I found myself defending Accountants, and now it's Economists! What next, Estate Agents?
Sad to see Economists being rubbished on the forum when the two who made the world rich were both British. Adam Smith invented Free Trade and the idea of Growth (which generates wealth), and John Maynard Keynes realised that money borrowed from the future could fix hard problems today. Despite cracks, both ideas have been extremely successful.
Economics is what I'd call a semi-science; although there are underlying rules that can be exploited, irrational human behaviour intrudes – everything between mob panic and financial Unicorns. What happens in the economy is due to a mix of rational and irrational thought. We are all emotional about money.
The economist's job is to discourage financial foolishness by improving decision making. What they do is imperfect and they get it wrong sometimes, or – more likely – unpopular advice is watered down. However, when it comes to the wealth of nations, an economist is a far better bet than man-in-pub. At least economists understand the basics. Financial management based on ignorance, prejudice, misunderstandings, or narrow personal experience is high-risk.
Putting it another way, criticism is cheap and easy. Any fool can do it, and – when irritated – people lash out. But, like any badly made cheap-tat, it's best if the quality of ideas meet minimum standards. Good criticisms come with with a viable alternative . You need to say 'This is what's wrong, here's a sensible alternative.' Then others can test the 'sensible alternative' to confirm it holds water and isn't flawed, or is just empty political vapouring.
I understand the frustration, but replacing economists, or any other kind of specialist, with unqualified blokes who happen to agree with you is a good way of making things worse.
Not everyone agrees with me. The philosopher Thomas Carlyle described economics as a 'Dismal Science' but he was a Scot with stomach ulcers…
