The most far-reaching consequence of the New Deal was that it redistributed the nation's wealth among the various social classes?

No. The most far reaching aspect of the new deal is that it slowed our growth out of a depression and created a further separation of classes by creating a non working class. The idea that you no longer had to work to survive created a class of people that believed they were entitled to rights not actually given them. As a result we have spirling Government entitlements to every conceivable group. We still have a working class of people that produce and pay taxes. We call these people upper middle class now. We also have a lower class that tries to "new deal" their "rights" to the working classes money. The 50% of us that work pay 97% of the Federal tax that supports the ruling class and the welfare class.
