FDR was a different era. Both the Democrats and Republicans are globalists and free traders now. Trump was lying when he said he could bring back manufacturing jobs from overseas. It's just not going to happen. US manufacturing is doing fine due to automation as well as cheap foreign labor--automation is a real problem for the future of the American worker. Furthermore, organized labor has been steadily crushed (by conservatives). If Trump somehow managed to enact a protectionist regime then prices at Walmart and Target would soar, sparking another populist revolt.

One solution Obama envisioned was government investment in green technologies that would create un-exportable jobs while addressing climate change and reducing dependence on foreign oil. Of course the right cried socialism and demagogued it to death.
