Tech is not hurting the heartland, the heartland is hurting itself. Techies consistently vote to increase their own taxes to help others left behind in the modern world. We have great health insurance and big retirement savings, yet we vote for more universal health care and to protect social security.
Heartland is the one voting to gut the safety net that they will need in the age of automation, and they are the ones voting for politicians that gut antitrust laws and allow for monopolies to emerge. They also vote to block help for people like themselves to have health insurance through medicaid if they fall on hard times. And then when we tell them that, they call us arrogant and threaten to hurt themselves even more. At some point you just gotta tell them to knock themselves out.
