In your letter you asked me about where I would live if I could choose.

Well, I would like to dwell in the sububs of a big and highly-developed city because I can get advantages of living in both places in that case.

The environmental issues are not urgent in the suburbs and I can easily find a well-paid job in a megacity.Although today more and more people leave villages and move to concrete jungles.

I think it's because healthcare system, education are better than in the counrtyside.

As for young Russian people,I don't think it is very easy for the majority of them to change where they live because they can have financial troubles.
