Why people prefer working in the government sector than the private and vice-versa?

From my own experience working in a government sector is better for the following :

1. great salaries and benefits.

2. safe. ( you feel safe in keeping the job)

3. better environment. 

 However working in the private sector is good because it was much more flexible.

1. Job security.

2. High status in society.

3. Benefits.
