[quote=cabal]

There is nothing illegal about knowingly selling an overpriced asset to an eager, voluntary buyer. Whether or not there is a moral component is subject to debate as I see valid arguments on both sides. .[/quote]

No, but there are laws against making false statements regarding the value of an asset

The punishment for making false statements or reports that overvalue an asset is also stated in the U.S. Code:[61]

Whoever knowingly makes any false statement or report, or willfully overvalues any land, property or security, for the purpose of influencing in any way…shall be fined not more than $1,000,000 or imprisoned not more than 30 years, or both.
