Opinion: The 2020 candidates’ economic plans make me question if I’m really a Democrat

I'm a registered Democrat in Iowa, where I have taught economics for more than 40 years. About once a week, some Democratic candidate campaigning for the fast-approaching caucuses shows up at a coffee shop or restaurant in my little prairie town seeking the support of me and my neighbors. Every couple of days, I get a text or a phone call from the local staff of Bernie, Cory or Mayor Pete, asking who I will caucus for in February.
