Well, there is a good reason some people think credit is a trap and living on it is a new form of slavery.
Unfortunately, there are folks who do not have much option and end up acquiring debt beyond their capacities,
I doubt it is a model which will "burst" any time soon, not yet.
It always feels so bad to be in such position but, its hard to sat there isn't of an option. Choosing to buy stuff on credit is very much an option and th other options are:
Seeking alternatives with lower price or
Having to wait a while to save up so you can afford just what you want.
It's not so obvious how buying of credit or getting getting to take loans to satisfy wants always seems like the easiest option. At least, you get to extend your payment through time but, its actually keeping keeping up with the payment that is always the issue and even in the given time, your likely to accumulate even more debts.
A typical spending g more than you can afford and that's a trend that builds up for sure.
Some business model it is and I don't think it's it's any time soon as well. It only gets better and better with easier ways to access them.
