You're not wrong, but on the other hand... the limit on direct contributions to federal campaigns is $5800. I can tell you from personal experience that this is enough to get a meeting with any senator or congressman except the most senior leadership (their price is about 10x more). So for about $3-4M/yr you can have every incumbent senator and representative on speed dial. They won't necessarily do your bidding, but they will return your calls.
If you give them $5800 they will start calling you to ask for more money. If it's a Congressman they will usually call you themselves. If it's a Senator they might call you personally, or they might have their campaign manager call. But from there it's pretty easy to get a meeting if you want one.
You don't even have to give $5800 in most cases. $1k is plenty to get the attention of junior congressmen and even some less well known senators.
Just to put all this in perspective, it's actually possible to get meetings with these people without giving them money, especially if you're a constituent. But the more money you give, the higher you move up in the priority queue, and it doesn't take much to move to the front of the line.
Just seconding everything you are saying. We dabbled in political contributions at my workplace for a project and it was easy to get a meeting with just about anyone (except our Senators who we didn't need to try) as long as we were flexible with scheduling.
It’s also important to note that a part of a politicians job is to meet with constituents, so getting a meeting is not per se nefarious. The issue is about how much more access you get if you are a big donor.
That's right. Also worth noting that if you want to influence policy (as opposed to getting personal favors) it is quite effective to call their office and speak to staffer, or write a letter. Every call and letter is assumed to represent the views of hundreds of people who couldn't be bothered to call or write. You don't have to be long-winded because the only result of your action will be that a staffer puts a tally mark on a sheet of paper, but the results of those tallies can occasionally move the needle on votes.
