I don't think only the only factor of inflation is going off of the gold standard.
The printed money was used to crush any social change around the world in fear of other socialist states forming in the supposedly "cold" war. Also, crushing unions reduced the percentage of pay that workers got for their labor, increasing that pay gap.
Corporations bribing governments allowed free trade across borders to countries with weaker environmental regulations. The corporations layed off and de-industrialized the USA while keeping the ability to profit from the hyperexploited labor of developing nations.
if you are citing Hyack who advocated for government regulations to favor businesses, why would any of these corporations not write the laws to crush small competitor competition, crush unions, control the federal reserve? The return on investment of lobbying the government to make moves in a corporation's favor is quite impressive. Why do you think that the boards of these corporations would not persue what is most profitable?
