You are not correct to surface-skim in order to wrongly label politics as 100% corrupt, folks. I suggest that you read the explosive 2017 book by Jane Mayer, "DARK MONEY: The Hidden History of the Billionaires Behind the Rise of the Radical Right" to see for yourselves the real villains---a couple of "selfish self above all else" (Ayn Rand, "Atlas Shrugged") spoiled-rotten greedy-gut rich kids by the name Koch (David and Charles) who want no parental [government] rules or regulations at all, seeking to have absolute power absolutely and to attract others of like mind to fulfill their anti-government anti-democracy corruption-plagued goals.
We, the people, rose up this past mid-term election to OVERRIDE the corruption and greed. We VOTED in record numbers to override the right-wing insanity that has threatened everything our already great representative democratic republic stands for---and there are 40 new Democrat-controlled seats in the House of Representatives because we did. And we, the American people, can do this again in the 2020 election as well. We can also collectively petition the Supreme Court to do the will of the people and REVERSE the radicalized right-wing Koch brother network's CITIZENS UNITED decision that gives billionaires' dollars more power than the VOICE OF THE PEOPLE.
The U.S. Constitution is the CULTURE of which you speak, Victor. The United States is a glorious and unique MELTING POT for all ethnicities, all cultures, all faith choices, and this is what sets us apart from every other nation on the planet. This is the CULTURE that we, the people (the REAL GOVERNMENT in our democratic representative republic) must protect with our activism.
