See, Johnny at al, no one can point to a single thing bad about the New Deal!
One of the reasons why the New Deal worked is because of the post-War boom. It's like with the Clinton era - his policies appeared to be great thanks to the dot com bubble, rise in housing and construction projects, rise in the Dow and Nasdaq, and general economic situation of the gay 90's - now people are starting to realize that treaties like NAFTA and WTO (GATT post 1994/1995 - where the US even criticized India, Brazil and Europe for restricting and overtaxing US imports - yet we caved anyway!) aren't helping us and have outsourced tens of thousands of jobs - like to China for example which has been disregarding nearly all of the things that it was supposed to do prior to joining, which it didn't and still isn't doing - like respecting intellectual property for one. Sure, they'll gladly take foreign investment, liberalize their banking policies, and create special economic zones to limit tariffs, but forget about adjusting their currency to it's real value.
I'll point out several issues with the New Deal before I get too wrapped up into NAFTA and the China/WTO issue:
Tripling of federal expenditures - (although this was offset by the post-War boom so it didn't matter too much but nonetheless set a bad precedent to the point where now presidents double, then triple the debt)
Government control of labor and prices - artificially inflating/deflating prices, meddling in people's private business
Created an environment that was more prone to bubble/boom and burst/bust - artificially controlling prices, propping up prices/labor costs, subsidizing corporations and certain industries
Undermining the free market and disregarding Adam Smith's Invisible Hand theories
Social security - good idea at first, a disaster right now (During the 1930's to around the 1960's I believe the statistic was something like we had 40 people supporting each beneficiary and now we have like 4 or something - I'll have to look up the exact numbers)
Increased economic regulation by the government - (pro's and con's on both sides - pro's for example in agriculture would be subsidizing the industry and providing farmers with livelihood, cons would be unrealistic market prices, higher costs footed by consumers - more prone to boom and busts in the commodity market)
Limited people's civil liberties and enlarged government's power to meddle in everything from food rationing, labor costs, consumer prices, etc.
Gave government offices to supporters of politicians who won elections - rather than people who should get those offices based on merit - further increased bureaucracy and government administration which is notoriously inefficient and wasteful of resources
Spending way too much money on public housing projects - which ended up being destroyed anyway with the residents moving into suburbs in future decades resulting in new crime waves in previously safe areas
White collar workers earning around the same as blue collar workers - despite having a higher level of education
Equality act for defense and government (you can't discriminate based on sex, race, creed, etc. but at the time was only for government - which I guess was good for those two industries - but now has spread to even private companies. If I have a company and want to only hire beautiful Polish girls that should be my right as it a private business) which later lead to bogus things like affirmative action - which ended up placing less qualified people into positions like firefighters and police just because of their skin color
Most importantly: The genesis of our welfare state and government bureaucracy so expanded that you can't fart without first getting a permit and paying a tax - which of course doesn't affect the public housing types, but rather those who actually work to provide for their family and make a decent home
I guess the New Deal did a few good things though: it got lots of people into the labor force like the old, young, women, minorities, etc., created the GI Bill, FDIC and increased the minimum wage a bit under FDR - which is a policy I am for... but up to a point.. $15 for jobs that are meant for part time high school students that now people have turned into careers is insanity.
I do believe that the government should have some role in the economy and the market - but very, very limited. It's not much a free market if the government controls nearly every aspect of it. That's why so many people establish companies in places like Nevada or New Jersey, Hong Kong, Macau and hide their money in Panama and Cayman Islands to get away from being overtaxed and over controlled. In Hong Kong, to establish a corporation it's literally a 2 page worksheet and a tiny fee. You can literally start up a company within a day or two - in the US the situation is infinitely more complex and yet globally our process of incorporation isn't even that bad.
