The education market is largely untapped and trillions are there to be won in this new "industry" by creating a marketplace from what was a public service with altruistic motives.
Their agenda is to foster a market and transition education into an industry from which great profits can be had for training worker drones who are specifically tailored to the job market. Employers no longer want to train employees - the numbers on that are so low that most people do not even think about employer training or realize that employers used to have full time instructors of their own. It's all about cost externalization - they externalized employee training and are acting like the education system is failing them when it never did their job for them.
Perfect is the enemy of good. Education in the past got us all the successes of today. But that isn't perfect, the perfect little snowflakes are not to blame... we have to get 100% success with every child and if not, it is NEVER their parents fault or the society. So lets completely revamp education which worked so well because it's not perfect. It's similar to how they destroyed the UK Postal System (Royal Mail) with tons of waste and destruction just so they could improve the service by a few % to become perfect. Now they've completely privatized it - it's still far from perfect...but new money can now corrupt the system so perfect now won't matter...
I don't care if 40% can't read out of high school; send those people to another school targeted at their failure within the old system. The major steps forward were done by a minority of people who thrived in the old education model -- not everybody is a genius and whatever was done that let those people shine and deliver the progress we had should be left alone. Don't kill the golden goose people! You can experiment on the teenagers or children who fail but you should leave the successful ones alone! You can also not claim that somebody who did poorly (Einstein) did not benefit from the system; it is foolishly simplistic to measure success by short term simplistic metrics. In reality, human learning and development is far from understood - it is far more of a black box than people realize. (besides, learning to cope with failure is a huge lesson to learn properly. )
One size does not fit all. Policy makers are always obsessed with making universal policies. Utopia is an incredibly evil goal.
