With proper financial background and support, this cycle can be broken.
If the one takes more and more loans to repay old ones and other previous financial obligations it is usually not a problem of only financial support. Usually they need help with financial literacy and they can reject it being frustrated with their bad conditions. To escape that circle first they need to understand what main problem is, and in the case of growing loans it is usually not just money, but planning and possibility of calculating a personal budget. And we unfortunately can see that some can't escape that circle...
I totally agree with this since I believe that being financial literate would ease the burden of taking loans. Having loans isn't really the problem, but it would escalate to be a problem if you don't plan and think of it further. Taking it requires taking consideration of everything, and if you found yourself in the verge of being addicted to it, you should have a plan to get away from it. Cycle would always seem to be unending since paying loans is not the only thing that we are considering every day. We have to live, so personal expenses should be considered and that would make the situation even harder. But I also agree that for some this cycle is not getting any close for it to end, which is very unfortunate to think, since we could have done something before you put yourself on that situation.
