Guys do not get carried away..no one walks free if he or she accepts gifts while assuming office in the United States. Have you seen any congress man or women walk free after taking gifts in the form of golf tickets or corporate jet flight etc answer is no..there is an ethics watch dog that oversee every public officials in the US congress..last time Charlie Rangle of NY appeared before the ethics hearing commission and reprimanded...remember Newts Gingrich...he was expelled from his post after his ethics violation..also Anthony Whiner of NY....etc are good examples...no one walks free after making ethical violations.
The reason why we do not see corruption in the USA is not only because there is ethics law .. but also because of the fact that the elected official prefers to guard his or her name and reputations ...plus many of these individuals are too rich to fall for little gifts you mentioned above. I would say when you are rich and educated you avoid making stupid mistakes such as taking bribes etc ....
I would like to give you a good example of IL gov Rob B. He wanted to sell Obama's Senate seat and you know what happened to him. I say in the USA the rules are unforced and respected by citizens. It is really hard and naive to compare Ethiopia to the big and advanced USA.
Fedup...you are really naive man...Obama or any other presidential candidate elected not because a certain billionaire wanted him to be... It is because of the amount of fund raised from individuals such as you and I that gave them the power to win elections. Stop watching those nonsense youtube clips that fabricate news simply to downplay our democracy. I can tell ....you Fedup are being duped by the youtube clips you watch every day ..those clips are organized by wacos. Too bad you belive them.
