Seems to me to be a far stretch to say that Donald Trump is draining the swamp with some of his nominations.
Take for example, Steven Mnuchin as Secretary of the Treasury. He may be a smart guy, but he is also part of the problem we've experienced in our recent history. He working for Goldman Sachs for 17 years and became a partner at Goldman in 1994.
After leaving Goldman, Steven Mnuchin was a principal in One West Bank, creating the bank after the 2008 collapse. His financial partners were George Soros, hedge fund manager John Paulson and others. They built their new bank out of a ruined, failed one – the failed housing lender IndyMac in 2009 for $1.6 billion. Mnuchin and Soros asked the government to bail them out and reportedly foreclosed on loans on around 36,000 homes. One of the homes was foreclosed on for a .27 cents payment error! The FDIC paid them $1.2 billion dollars for the foreclosures. The bank was renamed OneWest and sold in 2015 to CIT Group for $3.4 billion.
Sounds like crony capitalism done by a Goldman Sachs type executive who helps himself to your money. He would be "the third Goldman alumnus to serve in the job, after Henry M. Paulson Jr., under President George W. Bush; and Robert E. Rubin, under President Bill Clinton" in the 2000s and 1990s, respectively.
Mnunchin will oversee the national debt, the IRS, banking regulations and sanctions. In other words, Wall Street will control all of these things.
This is not the kind of people we need in the Trump cabinet. Instead of draining the swamp, Trump is filling the swamp with his own swamp creatures.
