I feel sorry for Yingluck. The youngest of the siblings, Thaksin the oldest, he made her CEO of SC Assets if I remember right. It gave her something to do. Never too bright, she couldn't even remember which Thai provinces were next to the sea, but her natural beauty and charm, her ease at talking to vendors, made her an instant hit with the working class.
Thaksin called her his clone, perhaps he was jealous of her popularity, reminding everyone she only became PM because of him.
And then she was forced into exile, the populist guaranteed subsidy for every grain of rice grown was clearly stupid as it resulted in widespread smuggling of rice from neighbouring countries claiming to be Thai rice but it wasn't her fault. She had only been in politics for 45 days!
She was a pawn who one day will be allowed back but her brother has two many enemies.
When Thaksin was PM he ruled by domination, financially and politically. A good leader will be decisive but also inclusive, considering all points if view.
Thaksin was too arrogant for that.
Even now he feels sorry for himself.
