Why USA has still few amount of hostels...

Hello!
My name is Aliaksandr Mikhasenak. I'm from Belarus.
There are many different hostels in Belarus and Russia (our neighbor) and I'm a co-founder of company which own a few local hostels.
I want to ask for a favor. It's really interesting for me to observe hostel's market in USA. I want ask you to share a general information about hostels and their position on USA rent market. As I understood there are no many hostels in USA. Could you tell me what the competition between hostels and hotels? What are prospects of development hostel's market?
I have a few variants to invest into US hostel in Atlanta. Because of it I want to explore  and inspect hostel's and rent market.
I will be very satisfied and grateful for your help and assistance!
Thank you!
