Indeed. The inefficiencies are indecent enough to make an economist blush.

You're wrong. The USPTO has an obligation to review any prior art that raises a substantial new question of patentability, even if the patent has already issued. Post-issuance, any person can request ex parte re-examination (even anonymously), and the cost is $2,520. That's a couple orders of magnitude cheaper than you asserted, so in the future, please refrain from commenting on matters about which you know nothing.
