As the Supreme Court considers canceling Biden's student-debt relief, here is how other rich countries handle student loans

• The Supreme Court is meeting to weigh Joe Biden's student-debt cancellation plans. 
• Biden wants to cancel up to $10,000 in student loans for those who earn less than $125,000 per year.
• In most other rich countries, student debt is easier to get written off than in the US.

The US Supreme Court will meet Thursday in another crucial test of President Joe Biden's plans to cancel billions in student debt.
