I'm currently reading a biography of one of the most famous and successful British rock bands. The core of the band met at a famous public school. They had:
1. Spare money to buy instruments and equipment, including vans and cars
2. Plenty of rehearsal opportunities - often in very large country houses or grand cottages where they stayed for free
3. Direct access to successful people in their immediate social circles
4. No immediate financial pressures. (Not that they were rich. But they were never in danger of starving or becoming homeless.)
They happened to be very talented. But without those opportunities the talent would not have been enough, and they would have had to join most of their peers in ordinary jobs.
Class is a network of opportunities that is denied to outsiders. It's also about learned social confidence within the network.
A few 'Well I made it so you can too' anecdotes are beside the point. A few people always do make it, no matter what.
The real issue is the number who don't, in spite of best efforts and hard work, and of the talent and hard work wasted in a culture of low social mobility.
The failures never appear in Fortune, but they're out there in their millions.
Being born into a better family gives you a better chance but it doesn't guarantee you anything, just like being born into a worse family gives you a worse chance but doesn't completely eliminate the chance of success for you. 90% of it is your effort in either case.
No, it's not anywhere near 90%. That is a number you pulled out of your ass that is diametrically opposed to every finding from the study described in the article.
Establishing that most/many people are effectively doomed from birth even in the US takes a lot of the validity out of the "personal responsibility" argument.
Even so it's not that simple. If you see your parents - and all the 'mature' people in your life - doing things a certain way, then that it is the "right" way. If what they are doing is complaining how they're ont getting what's rightfully there's (vs working to make it something they earn) -- then you're going to believe that too.
In order to be able to put in the effort required, you first have to have your eyes opened to the fact that there are better ways of doing things than what you're living with every day. WOrse, you have to accept that the people you've been looking up to may be wrong about important, fundamental things.
That hurdle - that awakening to possibility - is so much bigger than any of the rest of the effort required, because people don't generally know what they don't know.
I think that's an over-simplification. Maybe better put as: 90% of successes required putting in a great effort.
But how many equal efforts did not result in success?
I think it's fair to consider the effort (which undoubtedly is less and less important to success the more resources you start with) a minimum barrier to entry. But I don't think it automatically follows that the effort you put into something is a very good gauge of success. Or even that it's a differentiator between success and failure.
You also can't possibly believe any significant part of the difference between Lebron James and lesser basketball pros is due to effort and dedication unless you assume everybody else is lazy and partying when Lebron is practicing. He is the best (or one of the best) out of hundreds of extremely dedicated professionals.
