What jobs still benefit from a man's physical strength anymore? Most things that need serious brawn use 'hydraulic muscles'? Soon women won't even ask us to twist the lid off jars anymore, there will be an iRobot for that. Where are men needed these days?

We automated away manliness. It's worth less these days. The least valued men are now valued even less. Frankly, I think these disaffected men should go back to the countryside where it's still relatively cheap and grown their own food and drugs. It's not economical to grow your own calories the old fashioned way, but neither is collecting welfare. And it'd be a heck of a lot gentler on the psyche to create something with your own hands. I remember Richard Feynman talking about researching topics that already had been written about just for the joy of discovery. It wasn't needed, but was done recreationally.
