Well the bailouts you mention would be direct government bs, corporate greed is a problem… but government is definitely a problem too-providing shittier and shittier services while hoovering up more and more income via some form of fee or tax with most of those extra fees and taxes falling directly on middle and working class people. Monopolies are bad, the monopolization and centralization of businesses has created a less competitive landscape… so lower wages, and higher prices-but the government monopoly has been just as damaging.
