You see an inefficient system. Companies see a way to hold onto the money for longer, which makes them better able to use that money elsewhere in the meantime like continuing to earn from investments, benefit slightly from inflation, and potentially make other decisions with that money. Holding onto 2k for a few extra days might not be a big deal, but when you do it for everything you pay out that can be a substantial benefit over time.
