I'm criticizing a system that incentives optimistic initial bids that are later revised up. A bad system doesn't need bad actors to produce bad outcomes. A $275 million bid ballooning to $500 million without any competitive pressure is a bad outcome.
American infrastructure costs are higher than production factors, e.g. land, material and labour cost differentials, explain [1]. Our auction mechanics are called out by experts as a big part of the problem.
