My take on Boris Johnson, and yes, I did vote for him, is lack of experience like the rest of his government. He and his government live in the protected bubble of Westminster and have no understanding or knowledge of how most of the British nation live.
My observation of government response in this pandemic is lack of experience and a really serious issue. Ministers running departments for which they have neither experience nor more importantly common-sense practical ability. A university degree does not make you an expert on all or any given topic – it is simply a measure of formal education ability. Years ago, a good education started you on the second rung of the ladder and you worked your way up gaining experience. I once read the greatest WW2 British Spy was a man originally working as a warehouse labourer in Suffolk.
From where I sit, government ministers should have served their apprenticeship in the real world for at least 20 years before being eligible to become a minister. And able to demonstrate by record an achieving progression throughout the period.
