I agree with you. At the same time, the economy was growing more under Obama's 2nd term than now, more jobs were created then than now. We've had economic growth for 11 years now.
Also, vast majority of Americans being paycheck to paycheck is not a good thing and the Fed backs this data up.
I think healthcare and corruption are the winning messages. Bernie's been talking more about what happened in 2017 when the GOP was one vote away from repealing the ACA in the Senate, knocking 32M off insurance, cutting Medicaid, putting budgets to cut Medicare, the administration supporting a lawsuit to repeal the entire ACA RIGHT NOW in court.
Which IMO shows him sort of 'moderating' his messaging as the primary goes on.
