Fourth turning is here 这本书又一次准确预测：
The last of these eras--the fourth turning--was always the most perilous, a period of civic upheaval and national mobilization as traumatic and transformative as the New Deal and World War II, the Civil War, or the American Revolution.
Now, right on schedule, our own fourth turning has arrived. And so Neil Howe has returned with an extraordinary new prediction. What we see all around us--the polarization, the growing threat of civil conflict and global war--will culminate by the early 2030s in a climax that poses great danger and yet also holds great promise, perhaps even bringing on America's next golden age. Every generation alive today will play a vital role in determining how this crisis is resolved, for good or ill.
