Hardware development has gotten much more efficient in the last 20 years across the board - both electronics and mechanics - but salaries haven't kept up.

On the electronics side, better modules like RPi's compute module, open source footprint libraries, and reference designs have significantly sped up development since I started twenty years ago. What used to take weeks or months in Altium can now be measured in days, especially if companies publish their reference designs in the application format instead of PDF. The turn around time and cost on PCBs have also dropped precipitously, to speak nothing of the turn key assembly that the fabs offer. Pretty much the only thing that has stayed the same is that MetCal induction soldering irons are still the best.

On the mechanics side, it's hard to appreciate just how much better vendors' CAD libraries have become, to the point where you can drag and drop Misumi/Mcmaster/etc parts from a Solidworks extension onto your assembly like it was Gary's Mod. 3D printing alone has made everything more efficient during development and has enabled many interesting production designs from rocket nozzles to turbojet engines.
