I disagree.
When you've grown up actually in poverty, where you had to drop out of the invitation to take an entrance exam for a private school because it was known that you wouldn't be able to afford the uniform, never mind any of the activities, despite the full bursary that you would have received (and seen somebody less able in your class get it despite their being 'rich' enough to own a house, have two cars and go on holiday every year), where you were persistently underweight, where you scratched your itchy ear during Physics to find there was a bleeping flea in there, where you looked forward to snow because it meant that the ice on the inside of the window blocked some of the draughts, where you can still remember every coat you ever owned and the feeling when you squelched home in shoes full of blood to be told off for ruining them/growing out of them, where your glasses broke and you spent the next 22 months without any because the NHS wouldn't pay for a second pair inside two years - and when the comments from other kids about you living in a bin were more accurate than they realised. Oh, and that you were constantly told that staying in school was not for the likes of you by your own family - duck me, was she minted.
To me, wealthy is having a coat, shoes that don't hurt you, a hat, gloves and scarf and a pair of glasses vaguely resembling your prescription. Oh, and being able to afford a single NHS prescription, rather than trying to work out which of the five things the GP says you need is the most important because you can't afford a prepayment certificate.
You might not say your family was wealthy - but I would. Because, to me, you were.
