Actually, I have no problem with inequality. Some people choose to, and some people don't. The degree of 'apathy' ingrained into Thai culture is accepted by almost everyone.
'Rice in the field...fish in the stream'.
It's no accident that the top 50 wealthiest families (are Chinese who immigrated to Thailand) have all the money. Thailand left the barn door open. I think this is called...'natural selection', and it happens in every specie.
There are several very famous publications from the 1930's with titles such as ..."Bangkok - The Chinese Problem". They knew it was happening, but they did not know what to do about it. And after 1949, with the accent of King Rama IX...who was half Chinese...
However, truth be told, Thailand is so very insignificant compared to what is coming for the UK, Europe, and the US.
