If the FAA could only assure the gliding and GA community that equipping with transponders and ADS-B would provide avoidance of midair collisions, perhaps there would be more acceptance. Even with a transponder, aircraft collide with each other. TCAS on airliners (mostly) is the only system that seems to assure a resolution to collisions.

GA that predominantly fly VFR and gliders would gain the most from Nextgen improvements by preventing midair collisions.

It seems that FAA's main thrust with Nextgen (adding a second tracking ADS-B system) is for THEIR BENEFIT to control traffic under postive control (IFR or VFR Advisories radar tracking). That is the premise and main policy motivating this change to transponders everywhere and ADS-B.

BTW, I do have empathy for those wishing to stay in gliding at the lowest cost, raising their family and educating their children. Adding transponders and ADS-B doesn't seem to have a sufficient cost benefit. My particular financial position allows me to add that equipment.
