Moreover, TR and the GOP progressive movement were fundamentally pro-free enterprise and not socialist in their thinking and aims. They were reformers, not radicals or revolutionaries. And they were strongly pro-American, with TR especially determined to see America's Navy become capable of global operations to protect American business and commerce.
Notably, from the Civil War until the Depression, the Democrats and Socialism were marginalized by the success of GOP policies and the effectiveness of GOP Presidents and Congresses. The Depression upended American politics and gave the Left a long era of power, growing roots and tendrils that remain in place and continue to sustain them.
TR wanted direct control of industry, with discretion for him to decide when/where/how - all in the name of the common man, of course.
And that doesn’t even get into his direct democracy and activist courts agenda, both for which this nation is still paying deeply.
