My home internet is 200Mbps symmetric, and this is not uncommon in my area. I could upgrade to 1Gbps, for about $20/mo more. Bandwidth in the cloud is highway robbery. Bandwidth to home is flat rate.
What you got is a 200Mbps connection to your provider (and still that's probably a lie, it's probably shared before reaching their endpoint), afterward it's fully shared with every other customer... that's just how the internet is made, you can't have a dedicated 1 gbps to every single server, that just doesn't make sense.
Thing is, the higher the requirements, the more expensive it is to support, that's simple math... If you got 10 000 clients that download 1 gbps, you need 10 tbps, it's even worse if they are all on the same service, that connection won't support this, believe me.
