I'll second what Ross said. Beyond that, I'll add that by the time socks reached more than 50 cents a pair the monthly pay of a private had probably gone to $16, the clothing allowance to $4, and a great many of the soldiers were looking at $400 Federal bounties, plus state and local signing bonuses. Still, I suspect that one way the Federal government managed to swing the bounties was by letting pay and allowances lag well behind inflation, which was really ramping up in '64-'65.
All of which is to say you can learn a lot just looking at socks.
