Lawyers are compensated better for their time than Amazon warehouse workers. The raffle tickets aren't for, you know, a performance bonus or anything of value, it's just a cheap gimmick.
I looked briefly and, correct me if you know better, but I believe The Law Store is a business partner of Walmart rather than being owned by it. So when you pay them you are not paying Walmart shareholders but its owners (who are lawyers)
In Poland, lawyers got deunionized to a large degree around 10 years ago, and the result is that most lawyers with private practices are no longer making great money, or are plain struggling. The only ones who make a very good living are those in niche specialisations, handling corporate interests.
Can you imagine how much more software developers would earn if we were unionized as lawyers are? If you couldn't practice without a license? If you needed to go school for $$$ before being licensed?
