The sitting on a pile of gold is just a fallacy, which I covered in my previous post.
The tweet is kind of interesting. What she is in effect saying is that it would be better to destroy the stock of amazon, and thus the company, in order to spread those resources out to the starving.
Let's put aside the fact that the free market has provided far more than enough food for everyone and that it is government violence that prevents those few starving people from getting it.
Instead, we can look at the fact that by a very objective measurement of existence, the world at large disagrees. The vast majority of people would rather have Amazon.com/.uk/.au/.whatever and have some starving people in the world (again, caused by violence) than not have Amazon.com and probably still have some starving people in the world.
It's like there is an inability to think beyond step 1 in whatever insane plan people hatch.
