I'd disagree, H1B prevailing wages are around $115k/yr now. That plus USCIS backlogs have started pushing WITCH to use the Canada pipeline instead (bring H1B type hires to Toronto, where developer wages are easily 60% of what they are stateside).
That said, companies who want rockstars with foreign citizenships have been heavily using the O-1 route now though. Even YC and VCs have been using it to help facilitate immigrant founders
