You also work for the Military Industrial Complex if you live in the U.S and contribute taxes.
Either way, voting for reformist candidates (for either way you support) in senate, house and local elections goes a long way.
The military industrial complex is, essentially, a mandatory relationship, though with significant problems leading to inefficiency and poor management decisions.
The way to fix this is through reform. It could be argued that the election of a private citizen with no government experience however significant experience in the private sector is evidence of actual voting in for change in the military leadership. Whether this translates to actual long term efficiency is yet to be seen.
