… is from pages 215-216 of the 2016 re-issue of my late colleague Don Lavoie’s superb 1985 volume National Economic Planning: What Is Left?:
The libertarian Left was opposed to the intervention by any government into the lives of anyone, domestic or foreign. Thus, it combined an adamant opposition to international interventionism with an equally adamant aversion to domestic economic intervention into the market process. Unrestrained trade and migration, domestically and internationally, are, they understood, perfectly compatible with economic and cultural development. Noninterventionism at home and abroad was the consistent principle of the radical liberals. Any ambition to plan society’s development was rejected as nothing more than a return to the society of status, power, and privilege.
