Going to jail because of debt

[The Raven]

Do you know somebody who couldn't pay his monthly bank payment and after few months he was sued and sent to jail? Banks are ruthless when it comes to this and law is supporting them very nice. This is  the reason I am very afraid of taking bigger loans. What if I lose the job and become unable to pay my monthly payment? Why would I end up in jail with real criminals? 

Do you think of this before asking for bank loan or you are sure you won't have an issue with payments?
