What kinds of savings rate does one need to take $100k/year in retirement? It seems unattainable without a two income high earning (physician level +) people.
One key determinant of earning power is the ability to plan ahead. Typically, the longer your planning horizon, the higher your income. Since most of the people on this forum tend to plan years ahead, they are an atypical group.
Another key aspect of retirement income is retirement age. If you have a good job and enjoy your work, you tend to retire later.
If you combine those characteristics, planning ahead, making more and retiring later, it is easy to retire on $100,000 per year. My wife and I will have over $60,000 in SS starting next year when I turn 70.
The problems come when you try to combine stretch goals like retiring early and having a high income. I suspect that it is quite difficult to retire at 35 with $100,000 a year indexed for inflation.
