Sugar is antibacterial, hence why honey can stay good like forever. It's a cheap way to increase shelf life that also makes people really like the food because we evolutionary seek that stuff out. It's not right though. We work long hours so convenient foods should allow us to buy back some time. But when they're all like this, you end up either having to do it yourself or risk your health. There should absolutely be limits. But with food costs as they are, who is going to fight for that? The alternatives are more expensive, or you reduce shelf life. It's much better regulated here in the EU but we too are still not there, obesity is still on the rise.
