The thing is, I know plenty of people that grew up without money that have gone on to make a good amount for themselves but without it becoming the pure center of their personality or their only motivation.
She's overcompensating, not because she's gone without prior but more so, I believe anyway, that it's so the general perception will be that she has a lot more wealth than she actually does. I mean tbh, who even refers to themselves as "rich" before owning property, or other fixed assets? Anybody with any sense when it comes to finances and/or credit scores etc will know that not having an overdraft isn't necessarily a good financial move. Those who need overdrafts, tend not to have them approved bcus they end up stuck in them but those who do not need them, tend to have them as they are able to afford them and having one that isn't particularly utilised is a good way to boost your credit and presents affordability to potential investors/loaners etc. If any thing her saying that naturally makes me assume that she can't stay out of an overdraft which is why she would forgo one once out of it. Alex is a absolute tit, buuuut he wasn't wrong when he said that people who talk about money so much, don't have it.
If she was as monied up as she is trying to make out then she could quite easily afford to buy a house in, near or outside of London or Birmingham or both. She definitely wouldn't be throwing money away on renting if she can afford to buy, especially at London prices. She's full of shite.
