Liberalisation of behaviour has been a characteristic of society in general - schools are part of society. Personally, I don't think that strict uniforms and competitive sport are necessary for good education (based on my experience working in schools abroad and some excellent schools in this country). Downgrading of exam thresholds has partly been a result of the privatisation of exam boards, who operate in a competitive market. We have NEVER had a one-size-fits comprehensive system in England. Local situations have always been affected by independent schools, faith schools, grammar schools and other schools with partially selective admissions policies. I'm not some left-wing loon by the way - I actually believe passionately that the education system should support every child to be the best that he/she can be. I believe that starving of funds for SEN and EOTAS provision has been a huge mistake.
However, my greatest concern is that current policies will result in public assets and curriculum control increasingly ending up in private hands - all happening underneath our noses and justified by a very narrow ideology. It really seems that few people know or care about what's going on.
The events at Kings Science Academy in Bradford fill me with foreboding:

Not only has the head been arrested for fraud, but the school's "patron" is a Conservative Vice Chairman and benefactor, who stands to make millions a year out of rent for the land on which the school is built. The education budget should be spent on the nitty gritty of teaching and learning, not on making people with little concern for education even richer.
Ironically, free schools and academies were "sold" to the public as being more accountable to local demand, whereas the reverse is true. Budgets and the curriculum are controlled by central government; parents have fewer places on governing bodies and any concerns have to be addressed to anonymous Whitehall mandarins.
