For the benefit of my non-Brit readers, or even my Brit readers if you are under 50 years of age, I'm All Right Jack was a very successful film made in 1959 starring Peter Sellers but including a cast of some of the very best character actors on British screens at that time. It was a satire on the utterly crapulous state of British industrial relations of the 1950s which, I might add, continued through the 1960s and gathered strength through the 1970s until the unions ran head first into 'that woman' in the '80s. Needless to say, British industrial productivity during those decades was abysmal. However, it is worth reminding ourselves that whilst the behavior of the unions was a disgrace they got away with what amounted to industrial murder by the weak-kneed, pathetic and incompetent(non)management of the day. In fact, looking back, it seems fairly clear that once the grim-faced 'Lord Gradgrinds' of the 19th century died off, their 20th century successors proved to be useless in a more sophisticated 20th century.
All of that is by way of drawing your attention to an excellent article by Jeremy Warner in The Telegraph in which he points out that since the 2008 crash productivity from British 'workers'(!) has been abysmal as this diagram shows:
The reasons he adduces to this sad state of affairs are varied but worth reading if only as proof of the belief that the law of unintended consequences rules supreme. For example, labor is cheap and plentiful in Britain and thus there is little incentive to squeeze more productivity from the working force. In France, on the other hand, the labor market is in a state of frozen stasis due to the eye-watering costs to employers if they dare to actually lay off a worker. Hence, French employers, knowing they face the might of the State if they try to expand by taking on new people and then try to lay them off, simply stick with what they have and squeeze as much out of them as they can - or use modern technology to improve their output.
In the meantime, 'Dim Dave' spends every opportunity boasting of how many jobs have been 'created'(!) under his government without mentioning that all these extra jobs are producing less and less, and anyway, most of them are going to foreign immigrants who think getting the minimum wage is a 'eureka!' moment. Meanwhile, of course, British management is happy to rest easy on supplying the British market with its insatiable desire for consumer products without bothering to undergo the trials and tribulations of breaking into new foreign markets.
Ah well, it's a British tradition, I guess, and you know how fond we are of tradition!
