The education system isn't that bad in Thailand, lots of posters here have a sense of superiority about their home countries being so much better, but this does not align with my observations. European youths are often vulgar and disrespectful (especially in the UK, IMO) so whatever those superior edication systems are teaching them, they are not teaching them to behave themselves (and most of them have sh*t jobs).
At least Thais have some respect for their elders, provided they had good parents. Because that is what it comes down to: the parents. People rely on the education system too much.
