Can the following article be used to prove that the government uses money for its own purposes and does not provide enough support for areas that...

It would be very difficult for you to use this article to
prove or support this point.  The article is simply a factual article about what
happened with very little to help you understand why it happened.  It also does not tell
us enough facts to really allow us to infer very much.

A
few problems with it include:

• It has very few
  quotes about why the riots happened.  We know that it was because of the new policy, but
  there's only one quote from a rioter and he talked about destroying the whole system of
  government.  There are not even any quotes from academics saying "here's why these riots
  happened."


• It does not tell us who is truly affected by
  the new policy.  Are there many poor people who had been going to college at a low cost
  and will not be able to afford the price increase?  Or are the people who are affected a
  bunch of middle class students who just didn't want to pay
  more?


• It doesn't tell us who was there rioting or
  protesting.  If they were all people from areas with "real needs" maybe we could use
  this to prove your point.  But we don't know who they
  were.


• Finally, this article has nothing in it to prove
  your point about what the government uses its money for.  We know that higher education
  will cost more, but what is the government going to do with the money it gets?  Is it
  going to put more towards the expense accounts of the MPs (as in the recent scandals) or
  it is going to use the money saved to improve the National Health Service?  The answer
  to this matters immensely in terms of whether the fee increases help prove your
  thesis.

Overall, then, this is not a good
article for proving the point you are trying to argue.
