To narrow the growing divide between the rich (who own a bigger and bigger slice of the wealth), and the working class and the poor. That isn't marxism. It isn't even very close to marxism.
When Karl Marx began to hypothesize that an economic revolution would occur, one of his primary concerns was the unequal distribution of wealth. He saw a capitalist society where there was terrible inequality. A small amount of people possessed a high percentage of all the money and income. What this did was create a larger and larger poor underclass. Marx theorized that this unequal division of wealth would eventually lead to a class revolution. While Marx's revolution failed his essential problem still exists. In America about 5% of the people possess 95% of the wealth. This leads to certain problems, foremost among them poverty and income equality. All of this eventually leads to the problem of lack of spending in an economy.
Karl Marx completely ignores that poor life choices, choosing to spend hedonistically instead of saving and investing in yourself can also cause dramatic wealth inequality, especially when the opportunities available to invest in yourself are abundant.
Wealth inequality in a land of free opportunity is largely driven by choice, not institutions. When those choices are taken away (such as the denial of school vouchers by the Oligarchy of Teachers) Then a functional, rational Government needs to strip the powers from those oligarchal monopolies.
The fact that the Federal Government is so large that the Oligarchy of Teachers now directly controls the government only proves that the government has become an oligarchy itself with its sole purpose being to maintain, consolidate, and expand on that power, in unison with its various oligarchal enablers (Elite lobbyists). The government no longer polices monopolies. The government now plays the role of corporate armed security.
This isn't the government the founding fathers envisioned.
