If single piloted aircraft result in ticket prices that are 50 cents cheaper, that's what most passengers will opt for.

Like it or not, we've made flying so safe that fatal large commercial passenger aircraft accidents in the US over the last decade can be counted on one hand. Southwest 1380 was the last commercial passenger fatality and that was a single passenger fatality on April 17 2018. I think you have to go all the way back to Comair 5191 in April 2006 to find another passenger fatality on commercial passenger aircraft (I've excluded cargo fatalities).
