I think this all depends on how much women are being promoted in engineering training and engineering careers in the US compared to other countries. For example, in the UK there is a massive drive towards women being given special access to grants and career progression in engineering (also all STEMM areas). In fact due to the way funding will be allocated in the near future, it will soon be very unusual to find a university in the UK that does not promote such schemes. These measures are long overdue and I think you will agree that promoting gender equality in this way will be a HUGE benefit to engineering and the economy.
