I haven't seen anyone "whingeing" or "whining" about the physical characteristics of Britain. The majority of people, of all political persuasions, appreciate that Britain has the most interesting, diverse and beautiful landscape.
Neither are they decrying our beautiful buildings,our museums, churches, ,etc etc, or the fact that Britain is noted for its wry humour and ability to laugh at itself.
That is a totally separate issue from that of its current governance where it has been reported that Britain is one of the most unequal countries in Europe:
Guardian May 2019
"Rising inequality in Britain risks putting the country on the same path as the US to become one of the most unequal nations on earth, according to a Nobel-prize winning economist.
Sir Angus Deaton is leading a landmark review of inequality in the UK amid fears that the country is at a tipping point due to a decade of stagnant pay growth for British workers. The Institute for Fiscal Studies thinktank, which is working with Deaton on the study, said the British-born economist would “point to the risk of the UK following the US” which has extreme inequality levels in pay, wealth and health.
Speaking to the Guardian at the launch of the study, he said: “There’s a real question about whether democratic capitalism is working, when it’s only working for part of the population." "
In this country, the poor and struggling have been punished whereas those that caused the 2008 meltdown have been richly rewarded. There is absolutely no disputing that all our public services are struggling to keep their heads above water. Most people need access to an effective and adequately funded NHS, state education and justice systems, emergency services, etc,etc, together with affordable and secure housing. Some people can opt out and purchase these amenities separately, but they are the minority.
