I grew up in the DCon capital of the world, friend. I have heard every iteration of the jingoist "spend or die" speech. I am fed, clothed, and housed by tax dollars spent on "expanding capability" and "maintaining status quo". It is not about security and freedom, it is about securing profits and freeing untapped investment. Do you think that DCon is somehow different than SV? Small groups of whip smart young people using the lost ideas of an older generation to carve out a slice of an expanding market. Information Technology and War Technology are two facets of the same gem.
Your original premise may be accurate, but i do not believe it is correct. The path you take effects the place you go in many ways, and not all of them are obvious or even observable at the moment of choosing.
Stop investing in start-ups and a couple of people will be a little less wealthy. Stop investing in the military and we and/or our way of live dies within a decade.
