Britney's gross is amazing.
We have to look at it from a different perspective.
Britney sold around 180K tickets and got a $27M gross.
Compare her to current Pop girl tours -
OTR Tour first 4 dates - 180K tickets sold; total gross: $20,580,452
Primastic World Tour first reported shows - 275K tickets sold; total gross: ~$27M
ArtRave first reported shows - 172K tickets sold; total gross: ~$14M
Britney's average ticket price is amazing and she's selling less tickets than all of them but getting higher grosses.
Obviously, the amount of shows is FAR larger in her case cuz she has to do like 5 - 15 shows to equal the capacity that they get with a few shows, or even one stadium date in Beyonce's case.
BUT for someone whose last tour was a decline from her previous one and was showing signs of slowing down touring-wise, this endeavor has proven very profitable for everyone involved. I mean, just imagine the savings they make from not having to book extensive travel for the ENTIRE crew + props + stage etc and then not having to pay the venues to book them cuz it's all in the same place AND not having to pay high insurance costs (the insurance policies involving a tour + possible accidents are insane - see: Onyx Hotel and knee incident).
This is the smartest thing they've done for Britney's career this decade.
and at this point she's not gonna get another hit without promo so .... she better WORK.
