Is the US a real democracy?

If the United States (US) were the real champion of democracy, why is the US government currently shut down over the controversy of giving oligarchs a tax break, instead of giving US citizens health care? Please click on the following link for more: https://youtu.be/HmggrrebDGI

If the US were a democracy, why are almost 40 million Americans living today in poverty, and another 201 million more are living from paycheck to paycheck, while 9 of the 10 richest men in the world are also Americans? Today, the bottom half of Chinese live two times better than the bottom half of Americans! Are you aware that over 90% of Chinese are satisfied with their one party communist political system, while only 35% of Americans are satisfied with their multiparty "democratic" political system?

If the US were a democracy, why does the US continue to ignore 43 United Nations resolutions demanding the immediate return of Puerto Rico's sovereignty to the Puerto Ricans? 6 million Puerto Ricans have abandoned their national territory (gentrification), and almost half of the 3 million people in Puerto Rico live in poverty too.

And, if the US were a democracy, why is it suddenly claiming today to support Taiwan's inalienable right to self-determination and independence, only because it wants to try to justify going to war against the People's Republic of China to colonize her too?

The US looks, talks and acts like an empire.

The US is a plutocracy!
