I stopped coming to this site because every thread turned into a war of words between two or more people. PLAY NICE AND AGREE TO DISAGREE OR SHUT UP. STAY ON SUBJECT AND STOP WASTING PEOPLES TIME WITH IDIOT ARGUMENT
That being said, Scotts is very very good at marketing. To quote PT Barnum, "Theres a sucker born every minute." Scotts makes billions off of this fact. You could be "The official lawn care company of major league baseball" if you wrote the MLB a big enough check. I don't know any serious pros that use the Scotts products available to homeowners. They DO make an excellent pro grade fert, but it is totally different from what they sell at the depot.
Their product is junk, all or mostly quick release. Which does cause excessive thatch build up. It also kills beneficial organisms in the soil, most of it leaches out and into the waterways and aquifers.
BUT, the goo news is, you can make some good coin off of it. Tine rake it, dethatch it, aerate the lawns. All of these are good money makers and can be done by unskilled labor. The debris composts down quickly and makes some nice compost too, which can be sold back to the same customers as a soil amendment
