In most EU countries when you want to take out a loan, the bank takes a look at your current status ( employment, expenses, family, etc.) and debt history stored by the central bank ( which is basically you had a loan of 10k for 5 years, don't own anything anymore) and judge based on that if you're credit worthy or not.
Let's look at it from a different perspective. If a coworker and I build a service in my garage from the ground up where I let users pay $100/mo month-to-month, $75/mo for a six month agreement, or $50/mo for a twelve month agreement, you're saying it's fine to agree to the twelve month term, get the 50% discount for a few months, and then cancel your card even though the only reason I offered such a steep discount in the first place is because you promised you'd pay me for twelve months?
I do not owe them the money yet they sold the debt. Nobody cares ... I now have a default on my credit reference.
The whole industry is crooked
