'more skills than Tenerife holiday rep'
Could you put the snobbery to one side for a minute, at all?
To answer your question, yes, life skills are important, but I'm looking at the state of Westminster's expensively privately educated politicians with one eyebrow raised.
Integrity, intelligence, ability, conviction, and acuity have absolutely fuck all to do with a private education and/or professional qualifications, ime.
I do think that 'professional politicians' are generally problematic, although I don't know if that's due to entry at a young age, or just lack of life experience. Certainly many of the younger politicians seem to be capable of really appalling judgement (Nadia Whittome, Mhairi Black, both 'babies of the house', both prone to terrible emotive reasoning, as is Lloyd Russell Moyle, also relatively young.)
