Clinton enthusiastically deregulated and shovelled wealth towards the rich. It's a process that's been going on since the 70s in the US, UK, and elsewhere, but it's been more extreme in some places than others. The Democrats have been just as bad as the Republicans in this process. Real wages have gone down over the last 30 years.
This graph is for the US. It is very similar to the graphs of many countries. Decline in Labour's share of wealth ever since the 50s, with steep decline since the late 90s. In the UK, we hit a peak in the 70s and declined from there.
This is the reality of the political economy. The only Democrat (and he's not even a real Democrat) I've heard talk about it is Bernie Sanders.
