Americans who are not apolitical still tend to think about politics in terms of the current crisis and the upcoming election. On the average, we don't have a ready grasp, I believe, on a realistic timeline for our political challenges. The toolkit of activism that has a chance for success requires voting, but much more.
It's not hard to see that political action that might change the quality of life is the work of generations.
See, for example, the United States section in the eight hour day/forty hour work week article on Wikipedia. Here we see that early episodes in the struggle took place in the 1790s and 1830s, continued steadily for decades, and even after the 1938 Fair Labor Standards Act the struggle has continued. For example, some employers have sought to avoid labor law standards by renaming employees as independent contractors, thereby seeming to grant themselves exemptions to aspects of established labor protection. After more than two centuries, the work goes on.
Powerful people know that any faddish activism will soon blow away in the breeze. No need for the powerful to pay much attention to activism that doesn't look ready for the very long haul. For the work of a generation, for starters.
