Now, clearly, the 50% tax can’t both be a fiscal lynching and an ineffective waste of time.
You’d think that someone writing regularly for a major national newspaper would be able to grapple with logic, wouldn’t you?
People threatened with lynching tend to change their behaviour. That’s the purpose of the threat of course. So if people do indeed change their behaviour (change their working patterns, work less, leave the country, whatever) the results can indeed be an ineffective waste of time in revenue raising terms precisely because people have been threatened with a fiscal lynching.
