What if light parties had 3 DPS instead of two?

Poverty is solved however by proper payment to workers, and redistribution of wealth to systems that need it among other things.

More precisely, the underlying issue of poverty is the constraint of resources - You can only procure so many goods from the planet and distribute them. And if some people are taking more goods in that distribution, others naturally will have less to compensate. Thus, poverty comes to be.

And that is the exact same issue with queue times. We have a constraint of role slots in a party. Tanks and Healers take a disproportionate large place in them, which leaves DPS yearning for slots. Thus queue times happen.

The difference lies in the fact that role slots do not have to be limited and thus, overpopulation is not an issue you need to concern yourself with.
