Why did the King of Thailand drive away his four capable sons and leave behind an incompetent younger son?

Because the four princes have outstanding abilities, Rama X is afraid that his son will usurp the throne. So the four princes were disinherited and expelled from the country.

These four princes and their mother Yuwa Xida all live in the United States. The eldest son also obtained a doctorate in aerospace science, the second son also received a doctorate in law and is currently a lawyer in New York, and the third son is a medical school After graduation, the fourth son has a master's degree in trade. Compared with Rama X, the four sons who were driven away were indeed outstanding in ability.

Although Thailand has a monarch, and even the monarch holds great real power, like most countries today, it insists on monogamy.

The old Thai King Bhumibol only married one wife in his life, and he grew old with her. Although he held a high position, there were no scandals in his life, and he has always been deeply loved by the Thai people. But his son Vajiralongkorn is different. As early as when he was a prince or crown prince, there were constant rumors of scandals. He also got married and divorced many times, and had one child after another.
