Prostitution can only be reduced if the rich elite begin to pay tax so that the lesser educated can get a salary they can live on. My gf is a registered nurse with a masters degree, her monthly salary is a princely 18k baht. Minimum wage is ostensibly 300 baht per day, but no stipulation of the number of hours a day. Thailand is not so cheap, but some single parents are trying to live on 9k baht per month. So even women with an "honest occupation" are often open to suggestion, they have no choice. Where I live a litre of milk can be bought for as little as 20 baht, in seven eleven in Thailand it costs more than the double for a litre. Prostitution in various forms is in Thailand for many decades to come.
