The article you posted is a good explanation,and I’m repeating the same reply I gave to another poster to which the only addition I’d make is to note that there is a larger incidence of monopolies/cartel allowed in Thailand ( Tesco ,Big C ,7-11 ,Makro all under one ownership) which would be disallowed by MMC (UK) or equivalent in western type economies.
The reality is that Thailand’s attempt in certain instances to buck those rules doesn’t in fact work. Product remains unsold/ sells less until a financial crisis dawns on the consciousness of the vendor. However that isn’t how the majority work. I’ve just returned from a stay in Phuket (same time as last year) where the Central owned apartment was double what I paid last year because of the much higher demand. That said , I got a cracking deal (well below normal rates) back then (they responded to poor demand)and this year was closer to normal.
In the end no one is ever insulated from economic reality .
