I have to disagree with you and I think your interpretation is a bit muddy. You talk as if they're pushing apprenticeships onto white children, but it says they'll provide more apprenticeships opportunities for all children.
Then you say
The other recommendations will help children of all races...free travel under 22. Promoting reading etc.
You say that white working class is the 'bulk of the population', so these ideas WILL help WWC children. Plus the article specifically says to make reading fluency a priority for white working class children, not all children as you say here. I do think maybe you need to give it another read.
I also just disagree on the principle, I think it's a good initiative. Not perfect, as someone else points out it would be better for it to be based on more quantitative data rather than qualitative. However there have been many other studies in this area that I'm sure will inform policy.
The academic route has been pushed for many years, including many schemes to benefit WWC children. Look at the number of people from working class backgrounds attending university now. I myself got a first generation scholar grant which is still available. It's been done for a long time but we're not seeing great outcomes from it in terms of careers and earning potential.
The other aspect is, as many others have said, it's a culture thing. Many studies have shown that non-white and immigrant parents place far more value on education, pass these values on and push their children with education, and WWC families value academia less. Obviously this is a general trend and I don't mean every single WWC family is like this.
But I think we need to meet people where they're at. If there are some families, regardless of demographic, who value vocational, physical, social, life skills more than academia, then let's set up opportunities they'll value and that our country needs. We need more trades, and you can earn very good money from them.
It's interesting to hear a right leaning person wanting the government to step in and do more, as I often see the right wanting less government involvement ('nanny state') and more individual responsibility.
