An electrician is a skilled job requiring a good level of education and can charge high rates, may run their own business. So not the same as an odd job man or unskilled labourer. We had a landscaper with a degree in horticulture who could no way be compared to a jobbing gardener , the plumber who owns Pimlico plumbers is a millionaire etc, so just because someone has a particular trade doesn’t mean they have poor education or low income. So I don’t understand the comments about the electrician having a nice house makes sense- he may have a similar or higher income than an academic, this would be taken into account by sophisticated sociological analysis.
Last weekend, in Rutland, the first statue in Britain of the late Elizabeth II was unveiled.
