An electoral democracy, we choose those that make the laws. Due to the 2 party system we don't have many options for when they fail to do what they claim they will.
A true democracy would empower each of us to do as you say, but that's not what's here.
Our republic is quite corrupt due to greed and power, as well... Not as corrupt as many countries out there, mind you, but it's alot worse than it should be.
We're starting to resemble a corporatocracy in many ways these days as a result of all this.
'Republic' is about whether or not you have kings. Democracy is as opposed to autocracy, with a few other *cracys between those poles.
America is a democratic republic; the United Kingdom is a democratic monarchy. The US has a broken democratic system that does a really bad job of electing the most preferred candidate. It's almost cheeky to call America democratic.
I dont capitulate to intellectually dishonest children. You very well know what's going on, and if not then I place exactly zero value to what someone as oblivious as that thinks. So either you already know, or you're not worth considering.
Erm... Larger by land mass? Yes. Larger by GDP? No. Larger by number of inhabitants? No. Larger by amount of vastly different cultures that somehow get stuff like this done whole very decidedly not being a hive mind? Also no.
Firstly, no one said that. Secondly if you think the amount of immigrant populations in europe are as large or as old as the ones in America you're understanding of history is even worse than what the Americans know. Europe now has migration like the US did 40+ years ago. The amount and blending of cultures in America is wildly larger than Europe. The fact that y'all are starting to get what the US has had for decades doesn't make Europe more diverse.
As an American, you're being silly. You've heard of the Silk Road? The Mediterranean? The Old World has been rubbing shoulders with each other since 4000+ years ago. We just got here in comparison.
So in other words: you have nothing to say other than putting two different sentences next to each other and implying they mean the same thing without explanation?
I mean, in terms of humans that's 2 generations, and since diversity and populations concern humans, that's a big head start. But you can keep applying off topic cliches if they help you feel better.
