"Actually, I just called one of my brokers and asked if they could lend my shares. He said yes. I asked if I could stop them from doing that. He said no"...
So, first, your broker tells you truthfully that he is violating his fiduciary responsibility to you by using your account to profit himself, while damaging your interest in doing so, because they've rigged their rules that way, and put it in the fine print on your account agreement... which you agreed to ???
And then, he tells you (incorrectly) that there is nothing you can do about that anyway... so don't worry about it...
And then, you believe him when he says "We wrote the rules so that we could profit from hurting you, but, "trust us," we would never do that to you"...
LOL!!!
