A really striking excerpt from a paper called 'Perfecting Tyranny...' quoted by Don Boudreaux:
Those who have developed a comparative advantage in innovating and implementing state-produced social control via foreign interventions will benefit in the form of higher wages by employing their unique human capital domestically. Specialists in state-produced social control are able to suggest and implement new techniques and organizational forms of state social control on the domestic population based on their experiences of doing the same to distant populations. The result is that domestic activities, whether in the public sector or the private sector, are influenced by the experiences and skills gained during the coercive foreign intervention. As this process unfolds, the distinction between the state-produced social control used abroad and state-produced social control used domestically becomes blurred.
Not sure I entirely agree but it is food for thought in these troubled times.
