What do you think to the example of a friend of mine, a bricklayer by trade, also skilled in electrics. Has bought a few houses which he has done up and now rents out covering the mortgages, a couple of them paid off outright.
Portfolio equity value exceeding £500k
Likely savings value and savings held in (for example) a classic car >£100k
Day to day the guy works on building sites, manual labour, will drink cheap lager in a wetherspoons(!), shops in Tesco.
Nothing wrong with any aspect of his personality, he is perfectly comfortable with his roots, but he would never call himself anything more than working class....
