The british got his GC in 40 days !!! not only 140

All my coworkers got I-140 approved in one month.
However, as there was not retrogression for the other contries. A lot of them had their plastic card in two-three months.
I had to wait seven more month to sumbit my I-485. Now the speed for processing I-485 is lower, I don't know how long to get the card!
It seems unfair to us!
