Look: if you took your car to a mechanic, and the mechanic's only response, ever, was "It's not my fault. I can't fix it. Oh, by the way, here's a gigantic bill." You'd soon stop taking your car to that mechanic. Blaming societal problems for failing to teach children to read is exactly analogous to the mechanic above. Even if true, that just means they're taking money under false pretenses. Taking money from people when you know you won't/can't provide the services you are offering is generally known as "fraud".
