T. Roosevelt was president when endemic corruption was crippling the US, and indeed helped start the process to deal with some of the corruption. But this was only the beginning. Now, with money in politics again, and endemic corruption in politics, with the 1% taking everything of the 99%, especially during COVID and under McConnell, I would agree that it's important to remember the approaches of T. Roosevelt, though they're outdated in the current climate. Three dacades following T. Roosevelt, the policies of Republicans and others failed to the point of the Great Depression. What was needed thereafter was a New Deal (a coalition under Franklin D. Roosevelt), whcih defined the progressive liberal movement and the American Dream that followed. The corruption we're facing now began under Regan, and as far back as Nixon and even Johnson. Even Clinton contributed to this corruption in a significant manner. Any progressive movement would have to challenge the main culprits of this corruption, which are the GOP (along with a few neo-liberals who've been ineffective, and to hell with the asshole Libertarians). Real world progressivisim must address the corruption by the 1%, on which Teddy would agree.
