i would say the person in your example is desperately trying to elevate or cling to middle class status, although their working class background is evident, they are constantly aware they are on the brink.
middle class people, often display what's called "conspicuous consumption" working full time, a brand-new (probably leased) flash car on the drive, designer labels hanging in the wardrobe, and credit-card's maxed out, expensive holidays. the middle class income is stretched to its limit to pay for these luxuries.
a middle-class family often undermines its own potential for wealth by overspending compared to what they earn, because they're concerned with measuring up to their neighbours in terms of how big their house is, what sort of car they drive and the price tag on the clothes they wear.
i don't applaud or resent their 'success'. i recognise that they are a self achiever, but also recognise that they are striving, often beyond their financial measn, to keep up with the jones' ane elevate their perceived class. the biggest financial challenges for those on the less privileged end of the spectrum is escaping from lower class income and spending, and elevating themselves to middle class.
a person of upper class (or wealth/status) will find that buying suits from asda, dricing around in an old range rover that they got a good deal on, and holidaying in the cotswolds does them well as they feel no need to demonstrate their success and wealth, more that they need to save what they have or spend it on their childrens education than on the trappings of wealth.
