Query: How can people have such high credit card debts?

Relevant passages:
 <=SEP=> "I'm not sure if the rules in Canada and the US are the same. I'm as amazed as you are by the amounts of debts people have, but I can see how this credit can be extended. Generally, with good credit history and above average pay - it is not unheard of to get about $100K credit limit with a bunch of credit cards. What you do with that after that depends on your own ability to manage your finances and discipline. Good credit history is defined by paying your credit cards on time with at least minimum payment amount (which is way lower than the actual statement amount). Above average pay is $60K+. So you can easily have tons of debt, yet be considered ""low risk"" with good credit history. And that's the most lucrative market for the credit card issuers - people who do not default, but also have debt and pay interest."

 <=SEP=> I would say you are typical.  The way people are able to build their available credit, then subsequently build their average balances is buy building their credit score.  According to FICO your credit score is made up as follows: Given that you had no history, and only new credit you are pretty much lacking in all areas.  What the typical person does, is get a card, pay on it for 6 months and assuming good history will either get an automatic bump; or, they can request a credit limit increase. Credit score has nothing to do with wealth or income.  So even if you had 100K in the bank you would likely still be facing the same issue.  The bank that holds the money might make an exception. It is very easy to see how a college student can build to 2000 or more.  They start out with a $200 balance to a department store and in about 6 months they get a real CC with a 500 balance and one to a second department store.  Given at least a decent payment history, that limit could easily increase above 2500 and there could be more then one card open.   Along the lines of what littleadv says, the companies even welcome some late payments.  The fees are more lucrative and they can bump the interest rate.  All is good as long as the payments are made. Getting students and children involved with credit cards is a goal of the industry.  They can obtain an emotional attachment that goes beyond good business reasoning.

 <=SEP=> I had $70K in credit card at one point.  Limited income, starting a business - it's the only credit available. (yes, all paid off now).

 <=SEP=> You must understand that not everyone has or can get credit cards. Consider that those who are in the the lowest 20-30% of income tend to have fewer credit cards (or none), and lower credit debt, although some have quite high credit card debt relative to their income.  So you really aren't comparing the same demographics (the population of all income earners, used to calculate average income, and the population of all credit card debt holders, are not the same groups of people). Once you remove those folks from consideration, then credit card usage may still average higher, but accept that it is unusual for people making less than $20K-30K/year to have much credit card debt. You must understand that wealth and income are two very different (although related) concepts. One must note that there are millions of people in the U.S. who have wealth; they have net assets of over $1M (excluding their homes). Many of those folks have assets greatly exceeding $1M. And although it might seem foolish to carry a large balance on their credit cards, they may have quite low interest rates, and simply find it simpler and more convenient to use credit cards in lieu of personal loans.  Suppose you have $2M in net assets, and want to buy a classic car or a diamond necklace.  Charging $30K and carrying the balance until a dividend check arrives may make sense. Understand also that not everyone makes the same choices, or good choices. Carrying a credit card balance may appear like a poor choice, especially when you are not wealthy, or have lower income. But suppose you have a high credit limit across several cards, and you need to handle a short-term financial challenge (car repair, layoff, medical bills, etc).  You might use the credit card to pay for that purchase, essentially financing an extraordinary event over a longer period of time.  And although having a balance of more than 5-10% of your monthly income may seem foolish to some, it may make sense to others. And some people choose to carry balances of 50% to 100% of their credit limit.  Others realize that keeping their credit utilization below 30%, 20%, or 10% of the credit limit is a better plan (both interest rate and risk wise).

 <=SEP=> In the United States, when applying for credit cards, proof of income is on an honor system. You can make $15k a year and write on your application that you make $150k a year. They don't check that value other than to have their computer systems figure out risk and you get a yes or no. It was traditionally easy to attain credit, but that got tightened in 2008/2009 with the housing crisis. This is starting to change again and credit is flowing much more easily.
