That is true. I'm not certain when rationing was implemented in Germany, however. There just doesn't seem to be a lot of unbias info available.
It doesn't matter when rationing began. Rationing was used by all sides during WWII. Nazi Germany didn't nationalize industry.
"The German economy, like those of many other western nations, suffered the effects of the
Great Depression with unemployment soaring around the
Wall Street Crash of 1929.
[1] When Hitler became Chancellor in 1933, he introduced policies aimed at improving the economy of Nazi Germany. The changes included privatization of state industries, autarky, and tariffs on imports. Wages increased by 10.9% in real terms during this period.[2]However, reduced foreign trade meant rationing in consumer goods like poultry, fruit, and clothing for many Germans.[3]
By the early 1940s, over 500 companies in key German industries had been nationalized, mostly accomplished through the creation of the
Reichswerke Hermann Göring in 1937.
[4] Multi-national industries in occupied territory were particularly targeted for state ownership, where the Reichswerke absorbed between approximately “50 – 60 per cent” of heavy industry in Czech and slightly less in Austria.
[5] Göring industrial empire was a major attempt towards “restricting private industrial capitalism and substituting a ‘völkisch’, state-run industrial economy.”
[6]
In 1934
Hjalmar Schacht, the Reich Minister of Economics, introduced the
Mefo bills, allowing Germany to rearm without spending
Reichsmarks but instead paying industry with
Mefo bills (Government IOU's) which they could trade with each other.
[7] Between 1933 and 1939 the total revenue amounted to 62 billion marks, whereas expenditure (at times comprising up to 60% rearmament costs) exceeded 101 billion, thus causing a huge deficit and national debt (reaching 38 billion marks in 1939 and coinciding with
Kristallnacht [November 1938] and with intensified
persecutions of Jews and the
outbreak of World War II.)
[8][9] By 1938 unemployment was practically extinct.

Does that sound familiar? It should. Republicans have long advocated for and propagated privatization. Trump is and has for the last year and a half advocated protectionism, e.g. increasing tariffs, just as the Nazi's did. Trump's tax cuts are expected to add 12 trillion dollars to the national debt. His infrastructure spending will add another trillion dollars to the national debt. As the stresses on Nazi Germany's economy grew, Nazi's were forced to nationalize industries out of necessity.
You should be concerned. We should all be concerned. The American right wing is looking a lot like Nazi Germany these days. They both are pushing protectionism. They both are pushing for massive government spending programs. They both are against democracy and individual freedoms like the freedom of speech, e.g. Trump's war on the 1st, 8th, and 14th amendments and the separation of powers.
It's kind of funny in a way. For the last 8 years Republicans have been deficit hawks, opposing any and all fiscal stimulus, even going so far as to attempt to cause a debt default on multiple occasions. Now, it's what deficit, and what debt? Republicans have suddenly developed a case of mass amnesia.
