Which front wheel is the drive wheel? I have uneven tread depth in the front and forgot to check which side before taking in for balance and rotation, so I don't know if they rotated the fronts to even out the wear.

 

I believe it is the drivers side.

It's an open diff, both front wheels pull the car until one slips.
Google how differentials work for a better understanding.

 

my right rear tire gets all the power.

 

Fwd doesnt torque load like a rwd solid axle. It will wear pretty evenly and wheelspin will be pretty random. I suspect you have a n alignment issue or you have a particular corner in your daily commute that wears a particular front tire faster.

 

Both wheels if lsd and whichever wheel has least grip for open diff neither contribute to uneven tire wear
