School funding money

Did you know that most schools spend their money on things like advertisements, dances, and sometimes unnecessary supplies?? I think based on this information stated above are the reasons why our school and many others just like it are poor and having more parents and students pay for the rise in school fees, class fees, sports, and other school activities. The schools like ours are poor or say they are poor but yet we still have the money to get supplies to have a dance and to have other things like buying into computer websites that cost lots of money when we could do something else to make our school less poor and to have more money to save rather that spent it on ridiculous things with high or expensive prices. 
There is also many other ways that the government and the schools can make more money and stop trying to con our parents and other people that pay for more things than they need to. I think either our government needs to give schools more funding money to help not only the schools but the students, teacher, and school managers. The government does fund as many schools as they say they do and the amount of money they are funding these schools with is definitely not enough to actually fund these schools. 
In my opinion I think that school have no money that is provided for them so they drain our parents pockets of all the money that they have and use it either iiresponsible or for one thing that is very pricey. I don't understand why like up at our high school they made this policy for next year that you will have to be in a advanced class if you want to take a college prep class in high school at all you would of have to have been in one or more advanced class from 6th grade on to get in a college prep class at all. Or you will have to pay to take that class and that also costs quite a bit of money again out of yours or your parents pocket. And I can tell you that those college prep classes are not cheap at all. 
And up at our high school you have to pay way more for sports than last year and even thou they cut some sports last year to and they raised the prices on the sports fees, school fees, and other school related activities or groups too. I don't get why the schools here are becoming worst and worst every year and still managing to keep the school running because by they way they act the school is so poor they can't even afford  some of the things like a couple of new desks for the class rooms that are needed. 
Schools you would believe that most money form the government and other policy money and funds would got towards the schools in all places around the world but little do we all know that only a little percentage of the money that the government received goes towards schools and our younger generations of education. Personally I think this is unacceptable because I thought one of the biggest things in all states and countries is education this is because education is what first thought of jobs and created the working of America and the building of many other things. 
All of our countries greatest achievements like electricity the light bulb, the first rocket created by NASA, and all kinds of jibs that build America to what it is today and made it possible to have success in the future all of these great achievements all started with the building of education. This should be one of our most prioritized thing in not only America but in all places everywhere. That's why schools should not be poor they should have lots of money that should go towards education, learning, and schools.
