An American can get a very sad and bad sandwich for about $20 in a mid sized American city. They can get a full meal with fresh ingredients in most of the rest of the world for $10 (no tip either). Some places even under $5.
An American can rent a dump in a high crime city for $2000 a month. They can get a nice home for $500 a month in many other countries.
An American can pay hundreds a month for health insurance that rejects their claims and covers absolutely nothing, resulting in a medical bill of tens of thousands of dollars. Medicines can cost thousands as well. They can pay out of pocket for treatment in another country and it'll cost hundreds, and medicine will cost a few bucks.
