That is far in excess of the estimates offered by the proponents of this legislation at the time it was enacted. I opposed it also on the further economic ground that the Mexican laborers brought into this country were exempted from the operation of the incometax laws. All Americans must pay taxes on their Incomes. but these migrant workers are exempt from our incometax laws. they are even given workmens compensation payments. in fact. they are put into a special category over and above that given to the American workers. I attacked it on the ground that it was unfair because of these exemptions. I think.
