With regard to letting agents be the contact, that is because many landlords pay managing agents to manage properties, rather than getting bogged down in this themselves. This is especially true if the landlord is not a professional landlord, but has another job.
I think that's the point. In the US, in New York at least, I think that becoming a landlord is seen as taking on a big responsibility, where it seems that in the UK it is seen as something you do to get cash, and your other responsilbilites take priority.
Of course, it depends on the individual. I'm sure there are landlords in both countries who bend over backwards for their tenants, and landlords in both countries who are jerks.
I think the difference is that in the US, the law takes the tenant more seriously, with the idea that when you become a landlord, you take on the responsibility for providing a home for another human being, vs. the idea that you are engaging in a potentially lucrative investment option.
A while back, here in the UK our boiler broke and we were without heat and hot water for, I believe, over a week. It was a nightmare just getting in contact with the letting agent.
In the US, if the problem hadn't been fixed within 24 hours or so, I would have reported to a city agency and the landlord would have been fined if he didn't get it fixed immediately.
If a tenant doesn't like this arrangement, they don't have to rent the property.

What if they can't afford to live anywhere else?
