Ps: I do not know if you did not describe the whole issue here, but you follow my response to employment-generating policies based on the economic mainstrean.
Employment generation policies depend in principle on the structural features of the country. The president may choose to create new industries or encourage those in which the country has relative advantage of production in relation to other countries. A strategic factor for the generation of jobs is to guarantee an economic and institutional environment conducive to foreign investment and reinvestment of companies. For this, the government must be transparent and signal clear rules to the market.
Justice Frank Murphy opposed the majority. He believed that military necessity was merely an excuse that could not conceal the racism at the heart of the restrictions. Hope this helps! :D
