The ~100+ billion number is revenue - cost of goods. Actual profit after _all_ expenses is around ~13 billion or so. Big number? Yes, but only around 3-4% profit margin. And it's been declining.
Walmart has 2.3 million employees. $13 billion doesn't make for huge pay increases when you've got that many people to cover.
