If you want to truly understand the difference. You'll have to travel far back in history.
America did not exist yet and Europe was a poor place. India and China were rich and had a huge trade surplus, they were getting richer and Europe was getting poorer. And they were not interested in invading other countries.
Europeans invaded and robbed India and Africa from where they got most of their wealth.
This wealth helped Europe industrialize.
During this time someone looking to travel to India accidentally discovered America.
I'll leave rest on you to research.
Fast forward today, American companies (facebook, google) have succeeded in extracting huge value from the European continent.
Partly due to their economic policies and immigration of talented labor from other countries.
Europeans do not welcome immigration, considering the fact they are the nations who've robbed developing nations.
And Europeans do not like it because they've rapidly aging population, they are not in a position to compete with America and rising nations (India/China etc...)
Europe is now in wealth preservation mode. They want to stop wealth from leaving their shores.
As Europeans come together to protect the wealth and they've somehow made a case for the welfare state.
Today, Europeans ride their moral high horse and advocate for high standards, but why should anyone give them any creditability when their roots are imperialism / plundering poor nations.
GDPR is yet another unreasonable and difficult to comply with policy coming out of Europe. It's their wealth preservation plan.
