There is no good reason why every service provider shouldn't be at 50 megabits down/upstream
Unless you're being fed by fibre then there is... DOCSIS cannot handle that kind of upstream performance without splitting the nodes to very small number of users and VDSL2 cannot provide that kind of upstream speed without very short loop lengths, a lot of people are on longer loop lengths that can barely handle 10Mbps up or less. You roll out 50Mbps up with DOCSIS without splitting the nodes very small and the tiny amount of capacity at the node will be congested in no time. These are technical limitations of the access technology. The situation will improve a bit with DOCSIS 3.1 and VDSL2 vectoring but these are a ways off.
Sorry to ruin your silly rant with facts.
