The post you are reporting:
Many, if not most, people who get a loan, have to have an income through employment, as well as a guarantor who has an income through employment.
So my point is, and this is probably the point in the article, so many who are paying rent or mortgage are paying far too much, and consequently can't meet the costs with their income.
As a result, when they can't get a bank loan, which may be because they already have a mortgage or a bank loan, or a bad credit history, they revert out of desperation to loan sharks.
What they pay on interest is a sheer disgrace to Society.
I strongly doubt they are simply over spending their budget. For example people with children: they know full well what they can afford and what not. So if you have to buy, for example, school clothes for a growing child to replace the clothes that no longer fit, and a new pair of shoes, can one just simply apply the advice: learn to budget?
The other point in the article is: the tendency to poverty and debt-slavery is growing.
So Simple-Simon explanations are simply of no value here! The economists have failed, the capitalist system has failed, and speculative house and rent prices, coupled with strangling interest rates on loans, are spiraling the Country into poverty.
