Arguably, cheating is now a normal every day part of society. Approximate 2/3rds of people have been cheated on in USA. Much higher in Asia. The sex industry in asia is absolutely massive and it’s primarily for married men. In Japan, only 65% of people say cheating is morally wrong.

But it’s usually don’t ask don’t tell, not explicit lying.

To give a specific example, I’m currently traveling in Vietnam, and an entire floor of my allegedly “5-star” hotel (the most expensive in the city) is reserved for prostitution. This is a smaller city with almost no foreign tourists. The rest of the hotel operates as normal, with a fancy breakfast served everyday 6-9am.
