The liberal ideal is that everyone should have fair access and fair opportunity. This is not equality fo result. Its equality of opportunity. There's a fundamental difference.
We used to be so proud that our country offered far more economic opportunities than the feudal system in Great Britain, with its royal family, princesses and dukes. But social mobility in the UK is higher than in the US. Our social rift is as big as it was in the 1920s.
The core principle is that we want an economy that works for everyone, not just for a small elite. We want equal opportunity, not equality of outcome. We want to make sure that there's upward mobility again, in our society and in our economy.
