Thomas Edison invented the light bulb.
Although we often associate him with the invention of the light bulb, this is not technically true, as several people actually pioneered lightbulbs before him. People like Joseph Swan, Humphrey Davy, and J.W. Starr actually invented the light bulb first. Edison simply improved their designs and made them more practical, which gave us the modern light bulb.
Most Americans also know that fact.
Germany is a social state. A lot of other European countries too. But of course there are authoritarian social states (China or Cuba). Socialism doesn't have a clear definition. You can consider the 3. Reich as Socialism.
Germany is once again being given over to the leftists, and as a consequence will likely be an authoritarian Muslim nation in your lifetime. Sweden has a personal income tax of over 50%, an awful lot to give up for "free healthcare."
And of course socialism historically kills its citizens in the millions.
Wow, study history much? You just spouted as much garbage as the Nazi party and don't even know it.
