Most young people are no longer proud to be Americans, poll finds

From the wikipedia article you didn't read:

The Marshall Plan's role in the rapid recovery of Western Europe has been debated. Most reject the idea that it alone miraculously revived Europe since the evidence shows that a general recovery was already underway. The Marshall Plan grants were provided at a rate that was not much higher in terms of flow than the previous UNRRA aid and represented less than 3% of the combined national income of the recipient countries between 1948 and 1951,[110] which would mean an increase in GDP growth of only 0.3%.[7] In addition, there is no correlation between the amount of aid received and the speed of recovery: both France and the United Kingdom received more aid, but West Germany recovered significantly faster.[7]

Criticism of the Marshall Plan became prominent among historians of the revisionist school, such as Walter LaFeber, during the 1960s and 1970s. They argued that the plan was American economic imperialism and that it was an attempt to gain control over Western Europe just as the Soviets controlled Eastern Europe economically through the Comecon. In a review of West Germany's economy from 1945 to 1951, German analyst Werner Abelshauser concluded that "foreign aid was not crucial in starting the recovery or in keeping it going". The economic recoveries of France, Italy, and Belgium, Cowen argues, began a few months before the flow of US money. Belgium, the country that relied earliest and most heavily on free-market economic policies after its liberation in 1944, experienced swift recovery and avoided the severe housing and food shortages seen in the rest of continental Europe.[132]

Former US Chairman of the Federal Reserve Bank Alan Greenspan gives most credit to German Chancellor Ludwig Erhard for Europe's economic recovery. Greenspan writes in his memoir The Age of Turbulence that Erhard's economic policies were the most important aspect of postwar Western European recovery, even outweighing the contributions of the Marshall Plan. He states that it was Erhard's reductions in economic regulations that permitted Germany's miraculous recovery, and that these policies also contributed to the recoveries of many other European countries. Its recovery is attributed to traditional economic stimuli, such as increases in investment, fueled by a high savings rate and low taxes. Japan saw a large infusion of US investment during the Korean War.[133]

compare the US to what France, the Netherlands, Belgium, and Portugal did trying to hang on to their colonies and extract as much wealth from them as possible. Not to mention how many citizens of those countries are proud of that!

I was not suggesting the people can't be proud of the not-good things their country does-- only that they shouldn't. Also: whataboutism never defends any given position or stance; don't rely on it too much, if at all.

I see you’re speaking for yourself.

I don't know what you mean. Are you saying that the United States isn't generally pretty racist and that I'm just projecting? Or was this just a halfhearted attempt at an ad hominem attack? Elaborate please.

This strongly implies this is something special about American people that isn't shared by the rest of humanity.

Be proud to be human because our heritage is international. Splitting us up into national identities is ridiculous and only holding us back.
