[...] At one end, tax evasion and cash hoarding have left US companies--particularly tech companies--with a vast amount of money to invest. This glut of corporate savings has--both directly and indirectly--combined with a loose monetary policy to strengthen the pursuit of riskier investments for the sake of a decent return. And at the other end, tax evasion is, by definition, a drain on government revenues and therefore has exacerbated austerity. The vast amount of tax money that goes missing in tax havens must be made up elsewhere. The result in further limitations on fiscal stimulus and a greater need for unorthodox monetary policies. Tax evasion, austerity, and extraordinary monetary policies are all mutually reinforcing.
one could argue that this tax evasion/avoidance isn't really that serious since the amount of tax to be paid is arbitrary anyway, and if it's all legal, then why does it matter? the response to that is less moral (for which the answer is obvious: corporations benefit from government infrastructure and thus should attempt to pay the set tax rate in good faith) and more about long-term efficiency ... a corporation operating in a state that has lower tax revenues will 1) have shittier infrastructure and 2) put the average person through more hardship, meaning that not only are they less likely to be able to afford to buy products, they are (hopefully) more likely to rise up and demand change, potentially at a disastrous cost for the corporation
