"The fair tax was not just something I cooked up. Frankly, 1)I wish I had. But it was designed by the leading economists from MIT, Boston University, Harvard, Stanford, people like Arthur Laffer, one of Reagan's key economic architects."

My question is regarding 1). Shouldn't it be "I wish I'd had"? It's obvious that the speaker regrets not having done it in the past not the unreal present.

So, it's "I wish I had (cooked it up)".
