How life in Thailand has changed in the last 50 years ?

Thailand in the last 50 years is very different from today. For example, Old Transport in Thailand didn't use the electric train (BTS.) but use just train and popular transport in the country was car.  International was airplane. Alternative energy wasn’t popular because fuel is price. The present, fuel is prices when compared to the past. Thailand have to use Alternative energy because the human is increasing every time but fuel is depreciating that made the fuel is expensive. Food and drink in the past, Thailand didn’t use to eat fast food e.g. Pizza, KFC, McDonald and others because It didn’t have in Thailand. When 50 years ago, The foods are safer than now because they didn’t use chemical to be ingredient. The current ones is bad luck because they don’t have chance to eat some food of Thailand that had in 50 year ago but now it is disappear from Thailand. Entertainment 50 years ago, TV was black - white screen and was rare entertainment. Popular entertainment was drama from radio. The drama made by Gatetip team was the most popular drama in that time. That is very different from today. Present, Popular entertainment is TV and it is color screen slim and smart. At night, night club is so popular too. Present, Working must to use English language more than 50 years ago because Thailand will institute the Association of Southeast Asian Nation that use English language to be main language for Communication. In the past, waking was easy to find but it hard to find in this time. In the present, Unemployed people are more because population increases and the cost of producing goods and services more expensive than the past. Health 50 year ago, Thailand didn’t have more Medicines and vaccines as the present but had disease and dangerous more than the present. Now Thailand has computer and internet to learn about your health, Medicines, vaccines, disease and other that your want to know but 50 year ago didn’t use to do that. Education in that time, Thailand didn’t use to take extra tutorial class but now it have everywhere ,a lot of type to learn and it’s popular for student in middle school. 50 year ago, the admission to University is easier than present. Now the admission to University is very hard and has a lot of test e.g. part, A-net, O-net, Gat and other.
