Nonhuman people (euphemisms for corporations) that front for a tiny number of successful (euphemism for the one percent) human people, who want to own everything (euphemistically called 'privatization'), have made Hillary Clinton fabulously rich. They have put over $125 million since 2001 into her own, personal bank account. 
CEOs of these mega-corporations (euphemisms for Masters of the Universe) appear to value her presence so much that they are willing to pay obscene amounts of money to hear her speak.
Neither the mega-corporations nor Hillary have said what makes her talks so valuable. Her 'speeches' were closed to the media and contractually required to have no recordings or transcripts. When asked recently if she would be willing to release the transcript of her speeches to Goldman Sachs (which paid her more than $600,000), she just laughed scornfully.  (Laughing being a euphemism for 'don't make me laugh'.)
But wasn't the request valid?
After all, 600 thousand dollars is nothing to laugh about, if there was a speech, it must have been some hot damn speech. Shouldn't she share what she knows with the American people too? After all she is running for president of the American people, isn't she? Not for the Presidency of Goldman Sachs.
Her secrecy about the speeches and the untoward, obscene payments (a quick calculation reveals they paid her an average of $9,571 per minute) puzzle some of us. Even those of us who are trying their best to trust her, and might even vote for her because of the dangers of electing a Republican president, that is if Sanders loses the primary to her. One might wonder why she should command such astounding fees when truth be told, she's no Winston Churchill, no Martin Luther King", no John F. Kennedy.
Hillary "earned" a total of $21.7 million for a total of 53 hours  of work over the last two years. This figure does not include "honoraria" from the Clinton Foundation (foundations being euphemisms for organizations dedicated to protecting the wealth and power of the one percent). Since the Clinton Foundation is a so-called charitable foundation, it does not have to disclose to the IRS what it pays to speakers (even if the fees are paid to her).
When asked by a reporter to see manuscripts of the speeches, Hillary could have said, "Sure! I'm so happy you're interested in them. I will also provide transcripts of my other speeches to Citigroup, and JPMorgan Chase, other Wall Street firms, big banks, and big pharma because I have absolutely nothing to hide."
But she didn't say that. And she won't release the transcripts.
