Well, kinda. Lobbying can be about simply informing a politician

Who lobbies. Corporations, trade associations, labor unions, nonprofits, universities, cities and states, and foreign governments all lobby. Some hire outside lobbying firms (often staffed by former members of Congress, congressional aides, or agency officials); others employ their own in-house government affairs staff. Last year, external firms took in $2.76 billion versus $2.46 billion for in-house operations, the first time on record that firms accounted for the majority of federal lobbying spending.

2.76 Billion.

Other sites put lobbying over 5 billion in 2005

There are only 13k registered lobbyists.

It is not a “good thing” that billionaires and their corporations pay billions to influence law.
