Membership Dues on TroopTrack

How do we explain the expectation of dues to new members? If a father has one son and he signs them up then he is paying $26 per year for his son. If that father becomes an RA or more then He has to pay an additional $26 for himself. Are these fees 100% for TroopTrack? or does any go to Trail Life? Why are the dues not more towards family unit than individual unit? Been getting a lot of weird looks from some new families when we have to explain that they have to pay for themselves on top of paying fees and dues for their sons.
Any assistance would be great!

Thank you,

The $26 is the TLUSA membership fee and is paid directly to TLUSA.
