I mean it’s a pretty simple logic. The economy is strong but people don’t feel like it’s strong because it’s only strong for those of the top. It’s that way because we spent the last 40 years cutting taxes for the rich, destroying regulations and economic safeguards, getting rid of safety nets, and allowing for the wealthiest to abuse the system. Why wouldn’t saying we want to fix that problem be the right course? Uprooting ancien regimes is the one thing liberals and leftists tradionally agree on.
