I'm going to unpack this a little. The second sentence does not actually follow from the question asked by the first sentence.
"Value" is a loaded term as used here. Not all value is economic. Most value has a degree of judgement involved. I may consider an outcome to be of high value where you see the outcome as low value, and vice versa.
"Reasonable market rates" is a peculiar term to use when speaking about things government does. There are things we want as a society that would not be adequately replaced by market solutions. Roads, for example.
Your answer to your question contains a logic error due to the language choices of the question. You disagree with the value versus the cost spent. That does not mean there was corruption. It just means you disagree. Other people can hold the opinion that the value was worth the cost.
I am not claiming that there is 0 corruption or waste ever in government. I am saying that there has been an effort to create a perception that there is far more corruption and waste than actually exists. That in turn is being used as justification for taking a wide variety of actions that would be hard to sell otherwise.
