It's still a bad job, and now it's deeply entangled with illegal immigration. That makes it hard to make it visible.

Famous last words while clicking 'Order now' on the Amazon website.

I haven't ordered from Amazon in 2 years. It is a lot easier than I thought it was going to be, though I understand it might not be easy for everyone.

It was sarcasm but do you use Amazon? I do think that it's hypocritical for people to actually be a customer while on the other hand participate in popular culture by throwing big words like oppression around.
