Just like the foundation affair, it's one of their usual tactics.
They have the power, so self-action would inevitably demean their status.
Of course, Harry Gordon is an outlier.
The series of things he did, if you explain them in detail, would probably make old man Gordon lose face.
But that's his grandson — he has to help him anyway.
It's not like he could just watch him go to prison or die, wouldn't that be even worse?
That's why old man Gordon said he only wanted a foundation from the Clegg Family.
Having spent his lifetime in the political circle, old man Gordon probably knows that his grandson is suicidal, but he can't overcome this psychological hurdle — he has to let the Clegg family lose face before he feels comfortable.
"In fact, the best thing would be if the Gordon Family hurt mom. Then we, the Clegg Family, would have a reason," Michael nodded, "We can monitor mom's every move, if anything happens to mom, hmm... the Gordons won't be able to live it down."
