Siam started off as a poor country and over the years foreign investment has flown into the country to take advantage of the low manpower cost. Manufacturing and agriculture are contributing to strong exports. Therefore poverty has decreased and the quality of life style has gone up. It will be very easy for a Thai girl to get a job away from the bars as compared to her parents' generation...
Also the population of Thailand is going down (Fertility rate of 1.9 - Source - The Economist, as compared to a sustaintence rate of 2.1) and people are having fewer and fewer children. Today I only know ONE TG who has three children...
In this overall scenario I see the economy growing strongly inspite of the political uncertainty and logically therefore, I predict that it will get more and more expensive for especially people from Europe and North America to have the same level of entertainment that is currently possible. It's not a matter of if, but when. I would give it 8 to 12 years... There will be restricitons and P4P will keep getting more and more difficult.More bars will be demolished to make way for shopping malls and condos... I just need to compare in my mind the Pattaya of 1996 when I first visited and today's Pattaya. Thai women too will become more demanding and there will be a day when their outlook will be similar to their sisters in the west...
Enjoy while it lasts guys...
