Why is it shameful to borrow money?

Owing to a series of unfortunate events (a common theme lately), my next paycheck will be delayed by up to a month. This is not the first time this has happened (although it should be the last) and as a result, my ohshit money has already been spent. I have illicitly gotten a small part-time side job, but it will not quite pay the bills.

Some friends and family have offered to loan me money and it looks like I have no choice other than to either accept their help (and pay them back as soon as this stupid check materializes) or pay some bills late and tack on late fees. I am awfully tempted to do the latter although it is totally apparent what a stupid idea that is.

This got me thinking about why exactly borrowing money and being in debt is considered shameful. Do you look down on people who borrow money? If so, why?
