>If there were some change they could enact which improves the "greater good" (whatever that is) at the cost of profit, they wouldn't. Simple as that.

Right, nobody thinks airports/airlines are altruistic organizations, but this specific complaint doesn't make any sense because the specific decision to board by sections is for the greater good. A moshpit where everybody boards at once benefits no one. In this case, "greater good" and "maximize profit" overlaps.

>yeah. Like a grandma with a tenuous command of the language and four kids. :)

Usually this would be handled by the airport, not the airlines. Moreover airports usually have criteria for which people can get assistance, and they can only help people that they think need assistance. It's easily to identify someone in a wheelchair, less easy to identify "grandma with a tenuous command of the language" without engaging in sterotyping/racial profiling.
