Well..you can't hire more developers if you're not getting customers, keeping them happy or paying your suppliers. So those other roles matter just as much as hiring a huge conclave of developers.
My hypothesis for US companies is that the number of non-techies supported by each US citizen engineer is going up at an even greater rate.
Your comment is based on the assumption that engineers cannot do any of the non-technical tasks a company has, and as an English major who is also an engineer, I think that's a false conception being perpetuated by people outside of engineering.
