Answer 1

Answer:

Yeah, you're CORRECT: class warfare and the growing power of concentrated capital

Explanation:

We just need to look at what each writer/thinker wrote and we'll understand their political approach. Edward Bellamy, Henry George, and Laurence Gronlund were aligned with Socialism, each one on their way, of course. Because of that, their vision about society and how evolution would happen is strictly based on this political point of view. That's the reason they're worried about class warfare, once Socialism address that this event is inevitable and necessary. Those authors wanted to create a different approach for this "class warfare", and a good destination for the capital.
