Having a $900 million loss carry over is not the same as destroying $900 million worth of wealth. 

If you look closely at the Clinton's taxes all of their revenue is parasitic in nature in other words they created nothing and sold off access and and in return were paid with bribes. Further, their taxes show that they gave a few million to charity but when you drill down you discover that the charity that they gave the money to in order to reduce their tax liability by $1 million was their own bill and Hillary foundation charity which the whole world knows did very little charity work outside of paying for the Clinton's lavish lifestyle. With the Clinton's long history of theft dishonesty and corruption it's more likey than not that they purposely dressed up their taxes in preparation of getting 4 more years to sell out the rest of us to the highest bidder
