Poor proletarian workers, especially minorities, did not have the resources to either run away to Canada, or the ability to subject their families to financial ruin by serving time in prison or leaving them behind.
The people who were dodging the draft were college educated labour aristocrats who had enough money themselves or from their families to keep their heads down in Canada until the draft blew over.
Should they have served time in prison or dodged the draft? Morally, absolutely. Materially? That’s where the idealism falls apart.
I promise you that conscripted privates were not benefiting materially in any way except through the indirect profiteering of the US by means of imperial acquisition.
The federal poverty line for an individual in 1976 was 1,375 dollars a year.
A private with less then 2 years active duty, or the standard conscription length, that solider made 83.20 a month, or 998.40 dollars a year. Pre-tax.
That’s not exactly swimming in cash, which contributed immensely to the plummeting of conscript moral by the 70s.
