Sadly, I find all that ludicrous, complacent "world-beating" guff entirely predictable. Johnson & co have been enacting the third generation of "clogs to clogs in three generations."
First generation does the clever stuff and puts the work in, gets the business started and builds it up.
Second generation inherits wealth and a functioning business, but also remembers the period before the wealth, and saw the work, judgment and input it took to create that wealth.
Third generation inherits the wealth and hasn't the first idea where the money came from or what went into acquiring it. Members suffer from an impenetrable superiority complex and imagine that their family is rich because of some innate virtue of being cleverer and better than others. They haven't a scooby how to run the business or of the need to put the hours in, and they treat the business like a cash cow and destroy it with repeated insane ideas.
The UK is in it's third generation, so to speak. Cameron & Osborne (more inherited wealth), were the first that stood out to me. Johnson, Cummings and their mob of elite little boys are more of the same – but on overdrive.
I've been down about this for a long time. There's much I disapprove of Blair for, but New Labour squared the circle by getting the UK to reinvent itself as a modern, post-imperial country, settling in to a new relationship with the world but still punching above its weight.
The Cameron/Osborne/Johnson/Cummings types have thrown it all away.
Farage and the other nostalgia-mongers lured people with a promise of Forward To The Past - when that past no longer exists because the UK is no longer HQ of the largest empire the world has ever seen.
So to me, Johnson's behaviour is completely consistent with the bigger picture. He's personally a narcissist, sure, so will always imagine himself individually to be superior. But he and his idiots are symptomatic of a larger problem.
