Every First Lady has a staff that gets paid. Care to point out the posts where you were angry about Laura Bush's staff or any other Republican First Lady's staff? Just for comparison, Laura Bush had about 18 people on her staff with annual salaries of $1.4 million.
Getting paid in lavish trips? The First Lady travels the world on behalf of the nation and I'm sure her mom went with her sometimes. Is it a perk? Sure. Is it a big deal? Hell no. Again, care to show me where you were outraged at past Republican First Ladies who traveled all over the world? And what if, gasp, they took a family member with them?
Here is a page that compares the two. It was made in 2013 so you can't see the last few years of Obama's presidency, but it gives you a good idea. In the first 4 years Michelle Obama took 11 trips overseas. In the first 4 years Laura Bush took 17. Where was your outrage as as Ms. Bush was galavanting around the globe on lavish trips?
Melania, so far, may have ditched some of the staff, but she made up for the cost difference by living in a completely different city for the first 4-5 months of Trump's presidency costing taxpayers about $8.5 million. Maybe she won't end up with a staff and she won't take on initiatives. That's fine. It doesn't mean that Michelle Obama did anything wrong.
It's okay to admit you are a partisan hack. The truth will set you free.
