Restricting access to creative expression

If my theory that the less opportunities one has to express creativity in ones work and play is inversely proportional to ones need to consume ( in the modern sense of the word) is correct – then it seems entirely plausible that established power structures would try to limit the creative educational opportunities available to the young soon to be consumers ( such as art, music, dance etc) which could increase their ability to express themselves creatively and therefore diminish their need to consume and thus threaten the current consumerist led economic structure on which the aforementioned powers rely.
