TBH, I don’t think it’s that complex. They’re all obsessed with accumulating wealth and power over others. The main differences are where they are from and how direct they are able to be in their pursuits under the constraints of their societies. Modern Western bourgeoise appear to envy those in Russia who seem to be able to take actions without needing PR. In the West, the working class aren’t accustomed to people “falling” out of windows and, occasionally, the Western bourgeoise sacrifice one of their own to maintain the illusion that laws apply to them (frequently with minimal actual consequences for the sacrificee).
I’ll go with FreeCAD. I’ve known about it for a while and tried it about 5-10 years ago but have given it another look as I try to get back into CAD stuff and hate the restrictive licenses of commercial products. It has come a LONG way and is far more intuitive to use than it used to be.
