Aw, I just love it when you're reduced to ad homs. It means you've run out of argument, and therefore enter denial to validate your beliefs.
You're right that WW2 changed a lot of things about America, but it didn't provide the constraints on capitalism that the New Deal did. SEC. State and Federal banking regulators. Glass Steagall act. SS. Unemployment insurance. FHA. FNMA. FDIC. And more.
Which Republicans despised all along, and gradually succeeded in largely dismantling or compromising to serve their purposes.

Not that you'll actually read it- It's not just soundbite slogans strung together like so much of the rightwing drivel presented as fact. Perhaps others who actually think will do so, however...
World Economy! Free Market! Reaganomics! Self-regulated banking! Cut Red Tape! Ownership Society! Creative Financing!
That's just a start, of course... It wasn't enough that deregulation of the S&L's cost the taxpayer upwards of $350B- huh-uhh. That was just a taste of things to come. And it hasn't been enough that the top 1% nearly tripled their share of national income from Saint Ronnie forward- huh-uhh! Or that America's financial elite has established a permanent subsidy for themselves by owning the national debt, collecting interest rather than paying taxes. They needed those tax breaks to, uhh, stimulate investment, yeh, that's it... which translated into offshoring jobs as fast as they possibly could...
When did all this really get rolling? When Ronnie suckered the electorate, that's when, and he's still suckering many today, even from the grave.
