I hold by my thesis that it is money that counts. The society you mix in and your acceptability is decided by how well off you are, what house you can afford, the car you drive.
I have seen different members of families of my acquaintance move up and down the social scale, sometimes with siblings going diametrically different directions, based on where their income takes them. In one case, a woman went into the finance industry, reached a senior level, lives in a smart part of London, and mixes with the great and good - her income, job status, house etc place her there. Her brother, dyslexic before it was recognised, drove a lorry all his working life, his children would be living in housing association homes, were it not for their wealthy aunt, who helped them buy a house. Their lifestyles and interests reflect their income, yet my friend's brother was privately educated. She passed her 11 plus and went to a state grammar school.
If you have the money, you will be absorbed into the society of your monetary equals, regardless of their 'breeding', education. If you have no money the same will happen. People move up and down the social order based on their income.
