There are countries in which, if you let in a contractor crew to your house to do any kind of work, you have to watch them like a hawk because they're likely to steal from you if you're not looking. Businesses will routinely take advantage of you not being careful and cheat you. etc. US and western Countries in general have little to no of that, and that enables a lot of trust. In Germany, it's even common for Internet shops to send goods to custmers before receiving payment (the customer can pay up to two weeks after getting e.g. their new iPhone or laptop). Think of how much scams that would generate in many third world countries.
