I doubt it costs thousands of £ to produce a designer handbag but no one goes round saying Louis Vuitton workers are immoral.
A luxury product, targetted at the rich with an upfront honest price tag, is not comparable to ripping off the poorest in our society.
A MacDonalds hamburger costs less than a penny to make but you don't call MacDonalds workers immoral.
Again, a luxury product, insofar as it is a "treat" meal, not staple food, and the price tag is an honest one.
You are completely ignoring how companies like Brighthouse do their best to hide the total repayment value in the smallest of small print, and the only reason why they've put it there at all is because the law compels them to. This goes beyond profit making, they are actually trying to deceive people when they are at their most vulnerable.
Credit unions are a possible option.They are not an absolute panacea when the washing machine suddenly breaks.
Under that circumstance, I would suggest a payday loan to pay for the appliance repair whilst you apply for the credit union loan, then pay off the payday loan ASAP using the credit union loan. Yes, you are borrowing from Peter to pay Paul, but when Peter offers a competitive interest rate and Paul offers instant cash, it's a sensible thing to do. I don't like payday loan companies much but I concede that credit unions can't provide an immediate loan.
