That might not be an accurate way to measure it, because "bankruptcy" can mean very different things by country.
In some countries, individuals often don't qualify for bankruptcy. In others you might be able to restructure your debts, but they might not be discharged. In some, you may need to give up significant possessions to pay for your debts.
The US, for all of its healthcare issues, actually has a relatively progressive and accessible bankruptcy system. The majority of people in the US who file Chapter 7 have all of their assets exempted from liquidation by law. For these people, bankruptcy is literally as simple as a matter of trading all of their debt for 10 years of a bad mark on their credit report.
