i understand what you are saying, i've been running routing nodes for years now and it is a problem. Before the big capacity growth we all milked big sinks like bitfinex with high fees and then just closed at 1vsat/byte.

on the bright side i've had chans on drains that haven't routed anything in more than a year starting to be active in the last months so if you are positioned in the right spots with growing adoption there might be more bidirectional trafficl
