After taking the loans for pleasure and lifestyle hope they have the means of paying them back because we cannot forget that part of it and with interest too. If someone is going to take a loan for investment knowing fully well that it will pay itself back or there is a source of paying it back before ripping the earnings from the loan later is ok but just taking a loan for pleasure, I don't see a sense in that.
Everything can have sense. If they have a good job with a good income, if they have some good investments which are not good to sell at the moment and they want to take a loan for leisure at the moment then why not? If they can afford that I think it is their business how they deal with their finance.
So finding a sense in a purpose of a loan is not a problem, the problem is when a loan is taken without understanding of how to pay the debt. And the reason of such a reckless loan is not always so important. Of course if you need to save life or health it can be a good reason, but in most other cases we should think about paying the debt before taking a loan.
