its going up by a 25%, not a quarter.
Example (I can't speak for all schools).. but in NY, a medium sized HS pays approx. 210K annually for Internet access and support. (based on today's rates.. that number should be, based on market rate, closer to 300-350K). (smaller schools will pay less (depending on region and bandwidth), and larger schools pay more.).
210,000 x 25% = 262,500 (or 52K more).. Now in the grand scheme of things... that may not SOUND like a lot, but 52K on a small (and increasingly smaller) budget means schools have some very hard choices.. (drop it in favour of other programs which may make it less effective for today's student, etc...). And keep in mind, with no cap, prices CAN go as high as they want (of course there is a point of you "kill the host").. but making them bleed to death is not going to benefit anyone either (but remember, they don't like public schools.. so none of this is really surprising)..
Put in charge of education, someone that wants to see public education gone.
Deprive it of federal funds
Use the FCC to remove pricing caps which allow for more expense (notice, available funds have gone down).
Use the decline in quality as "proof" of why public schools should be abandoned..
Rinse and repeat until the problem goes away on its own.. or parents (en mass) vote to eliminate it.
