Cheers. Its what I saw with my own 2 eyes while I was there. Old bald fat Farangs with ugly, older low class Thai Hookers from Isaan.
Thai girls (WL or normal) are all the same at end of the day. Just doing what they can to survive. There's a famous saying in Thailand - "Money number one".
Only difference is, high class Thai girls just aim higher and go for high net worth guys (usually other Chinese-Thai's from Business/Political families).
While Isaan girls only choice (especially if she already has kids) are the old bald fat Farangs as no Thai guy in his right mind will want a single mother with kids from another man
