Really, there was a period when everybody was just switching over to broadband where they could essentially give everybody unlimited because there just wasn't that much content out there to saturate the network with. Now, with the amount of stuff delivered online, it's quite easy to go through quite a lot of bandwidth. My kids were eating up a ton of bandwidth watching YouTube videos on their iPods. I set a speed limit on those devices in my router, to about 1 mbit/s and was able to cut their usage to 1/3 of what it was. If there was no limits, people would end up using a lot more bandwidth than they currently do. I have my Netflix set to low quality most of the time because if I don't, it eats bandwidth, and I don't really care most of the time when I'm watching on my tablet. If I had unlimited internet I would probably just leave it on HD all the time, and not set any limits on my kids YouTube, and we could probably easily get to 500 GB per month of usage. Having a limit forces people to think about how they utiilize the resources they are paying for.
224 units is not enough to build even an elementary school around
Why not? If the housing is meant for families, let's assume a modest 60 percent of the houses have families, and that they each have 2.3 children. That's a total of 309 children. My kids go to a school of about 350 kids. I understand that in some places they have huge schools with thousands of kids, but I really don't see the advantage of that. Smaller schools where everybody knows everybody have a lot of appeal.
If all else fails, lower your standards.
