Half the stuff people are getting through there isn't essentials anyway... no one NEEDS a flat screen TV (there are tonnes of old-style ones on Freecycle - I've got our old one I keep meaning to put on there FFS), no one NEEDS a Playstation3 - yes you might need a washing machine or a cooker - but I see tonnes of very low priced ones outside the second hand shops on our local high street - just people want the snob value of having a new one.
My washing machine btw which so far I've got about 7 years out of cost me the princely sum of £20 when I rescued it from a friend's garden where it was awaiting the binman, got it fixed (the wally had jammed it up by putting too much powder in) and it's been going strong ever since! Yes we have nice shiny electrical stuff (I'm an unashamed gadget nut) but we saved for things and bought them when we had the money - not doing it arse backwards which seems to be the way these days! I think the only stuff we have on credit at the moment are our PCs which are on a buy now pay next year deal and the money for them is sat in an ISA making a bit of interest until then.
People have screwed up priorities though - my cousin is the sort who'd be the BrightHouse queen - she thinks it's her fundamental right to have stuff NOW, without thinking it through and prioritizing things (taken us a decade to hammer home the fact that your rent is not an optional extra to pay when you can be bothered). None of it's stuff she needs - heck, no one in the family would see her out a washing machine or anything like that - but games consoles, fancy tellys and the like.
You can talk about preying on the vulnerable all you want - but they're not THAT flipping vulnerable if they're getting themselves into this for a flipping Playstation.
The one thing you CAN reasonably argue is there's a need for better financial education within schools in regards to things like interest rates on loans and the like. But at the end of the day - they're providing quite a high-risk financial investment and the interest rates reflect that (same as we're in the middle of getting a mortgage as first time buyers - smaller deposit so we're going to get less awesome interest rates)... a fairly sizeable chunk of their client base probably WILL default and not pay - however much I hate the stereotyping of people in privately rented houses (as we've rented for years), they're more mobile and harder to trace.
