Today the main barriers to further progress toward gender equity no longer lie in people’s personal attitudes and relationships. Instead, structural impediments prevent people from acting on their egalitarian values, forcing men and women into personal accommodations and rationalizations that do not reflect their preferences. The gender revolution is not in a stall. It has hit a wall.

In today’s political climate, it’s startling to remember that 80 years ago, in 1933, the Senate overwhelmingly voted to establish a 30-hour workweek. The bill failed in the House, but five years later the Fair Labor Standards Act of 1938 gave Americans a statutory 40-hour workweek. By the 1960s, American workers spent less time on the job than their counterparts in Europe and Japan.
