People on top of hierarchies find all sorts of rationalizations to lie. Sometimes it is because they just can, or they want more resources than they currently have, or they want to convince others that they deserve to be on top and everyone else deserves to be on the bottom.
Donald Trump has been caught in numerous lies, but now it appears that his wife Melania Trump is made of the same cloth.
Last night in her speech in front of the Republican National Convention, she was found to have lifted parts of her speech from that of Michelle Obama in the same situation a few years ago.
Now apparently she also made up her college degree, in that she has said she has a degree in design and architecture at University in Slovenia, but her biographers say she dropped out her freshman year.
