me..? personal experience..

I've seen popular and thriving Music Technology and Performance courses in FE colleges, Universities, Schools, etc from the mid 90s to mid 00s..

.. coincedently under a Labour Government...

The part of your post that I called out as bollocks is:

" It is seen by the so called "liberal" left as elitists and therefore it must be expunged from the schools and Universities."

Apart from that groundless bias, I'm in accord with your views on the importance of music to our culture,

So, I confidently presume, are millions of other left and liberal inclined musicians....
