Please correct my essay!! About Japanese society

I think there's a tendency in Japan where we're expected to keep working for a certain company from the begining of our career to the until retirement.
However, I don't think that's a very good idea because I think it makes it tougher for you to find a wide variety of jobs that fit you.

In Japan, it is almost impossible to get better jobs once you quit the your previous job.
For the unfortunate economical trait, even though you ever get in trouble with your boss, or you can't find somebody who is compatible with, if you lead a healthy life, there's no other way but continue the work.
You would have to narrow down your options on your own for these reasons.
I think it's very ridiculous of you.

In many foreign countries except Japan, it is normal to switch jobs frequently and to like fly travel across the country to have interviews and so on.
They usually have many accomodations and flexibilities in the job hunting, and I think we should put those things into our society.

I'd be happy if I can get some feedback on my essey.
