I doubt many conventional guys will go broke because of tillage but it certainly doesn't help if you're strained for cash.
The past 5 yrs there has been a pretty steady conversion to no-till beans in this area. If the pace stays the same there won't be much conventional till beans around here in another 5 yrs. The switch is probably related to the ISU on farm field trials in the area that have consistently shown no yield increase from doing tillage for beans.
