I don't really understand that lobbying thing, who is paying who to officially make life worse for citizens and how this is justified? PS: I'm not american.
Anyone can lobby and so groups who have similar interests raise funds to send people to speak to government officials about what they would like to see done by the government. It's pretty simple.
Instead of a government for the People, the People, and of the People, it's actually a government for the Opulent Minority, by the Opulent Minority and of the Opulent Minority.
James Madison stated: "Landholders ought to have a share in the government, to support these invaluable interests, and to balance and check the other. They ought to be so constituted as to protect the minority of the opulent against the majority. The senate, therefore, ought to be this body; and to answer these purposes, they ought to have permanency and stability."
