I know this thesis of simplisme, but I don't buy it. Or rather, there's nothing around it. People are xenophobe or racist since the dawn of humanity. As you put it, the problem is disenfranchised people, but the solution is how to avoid to disenfranchised them.

Fascist leaders naturally arise when people are looking for solutions to their basic problems. These basic problems are housing, food, security, health,...

In some way we are indeed fighting some instinct of racism, an instinct that has us focus on a smaller group of people we care or understand. The bigger the problems, the smaller the group we focus on.

As for the technology, I firmly disagree still. The disconnect to me would be from the bullshit jobs (a lot of work doesn't serve society but the holy growth). That is one disconnect. The feeling that the rich have the society work for them and the people have to work for that and then find what they need to live is another disconnect. The intensity of work that prevent socialisation in the name of productivity is a disconnect. The lies and advertising for things you don't care much. The philosophy that every activity must cost something.

As for technology, people are saying what you're saying at least since we invented books. Don quichotte is exactly about this.
