I’m a pluralist. I believe in capitalism and socialism. Bad leaders of government will ruin either economic system. Good leaders will make either system work by incorporation both.
Critics and advocates of either economic system can easily find examples to prove their points. Norway or Russia. Venesuala or Sweeden. Why pick other nations for proof? Just look at our own U.S. history since 1919 for the right answers.
We developed excellent corporations, a great banking system, consumer protection agencies, etc. We also got Social Security, unemployment insurance, the Fair Labor Standards Act and so much more.
Progressives lose support by attacking capitalism and are easy targets for the socialism label.
Just point out that Republicans think any government policy that benefits workers, the middle class and poor is Socialism. Policies that benefit business owners and the wealthy is capitalism.
Imbalances always occur and good leaders enact tax and labor policies that can correct those imbalances.
A pluralist economy benefits both appropriately, or as well as can be expected.
