upper class arrivals miami and back at lhr

ok, so i am expecting the world, and it aint gunna happen, but i have to ask, even if it sounds errrr dumb 
so when you arrive in miami, is there any possibile chance, that there is a seperate line for upper class/first class arrivals to go through us immigration faster, or are you queing with the brat in a pushchair on a 1 fare?
and yes, if this (fast track) is only summat in a dream, is there any upper class perk when arriving back at LHR - as in faster through uk arrivals/passport control ?
I know wake up smell the coffee, but hey, if i dont ask, would feel a right plonker if there was such a thing as fast track for upper class/first class arrivals in Miami and i wasted hours in a que i could have avoided just by knowing where to go
Failing that - anyone know the cost of a private jet to a private airfield - i am SO doing the lottery !!!!
