If company expects 60+ hours per week, and not just in some rare bursts, they will almost never come to senses and scale back to some normal work/life balance. You just need to leave.
And if there's rare bursts, then someone made a mistake.
A lack of planning on your part does not constitute an emergency on mine.
Work steady hours, and the "output" becomes predictable (this is what agile methodologies are also about - predictability), which allows for better planning. Working 60+ hours means the output becomes very unpredictable. I mean people will crack and either leave or become overworked at that point, and now there's an even bigger problem.
