What is something terrible about Korea

The problem in South Korea is there are traffic congestion and traffic accidents.
Due to traffic congestion, drivers fight, produce a lot of traffic accidents and many people are hurt and killed.
And makes heat worse due to exhaust coming from many cars.
Also in the suvway, bus, taxi people who are doing bad actions are increasing.
For example it's serious that 막말녀(the women who swear) acts impolite to adults and acts those damage others are really increasing.
Finally biggest problem is the education of Korea.
As bad education policy, students, study very hard but still get low grades.
Because of these, a lot of suicide and mother's enthusiasm also grows on children struggles.
While there are many problem in South Korea.
I think the biggest problems are these three.
