Not saying they are. What I am saying is subtly different.
I come from a very poor background - in that my dad grew up in the village walking many kilometers to school with no shoes. So not UK poor - much more poorer than that. How he ended up wealthy is via education. Specifically an African-government funded academic scholarship to a London university. Changed the course for our family
The scholarships I speak about to the US are very competitive - so not available enmasse. However, they are academic or other - so meritocratic. And yes, it tends to be those with means that are aware of these things especially in the UK. Where my family is from - it is the opposite. The lower middle classes and educated poor are the ones that research and look for these opportunities, especially since the Internet. They are indeed vehicles of social mobility for the individual but not the strategy for the country.
I hope you don't take this personally, but there seems to be an aversion to business terms by Brits. It seems to imply some sort of motivational speaker vibe, as opposed to what the words mean at face value. I am in healthcare, so not a financier/business person. Ultimately- I believe our young people can deliver growth to the economy, that people are paid too little in general in the UK, that aspiration is low. And I see many threads on here where people are told they don't need more, not to go for that promotion, one life to live etc. It seems pervasive. Someone needs to be pushing the reality that the more senior you are, the more control over your time and your life and the more choices you have. Hence why I am bullish about changing the culture, expanding minds and horizons. Even if I sound like an American motivational speaker on the take!
