Some work standards have discretion built in, e.g. a retail buyer may be permitted to buy up to 10,000 worth of goods each month, but otherwise left free to decide the range of goods to buy. A manager of a fast-food hamburger joint may hacve some discretion over staff rotas but none in terms of changing the menus or the decor and displays within the restaurant. You may be failing to recognise the value gained. More goods and services are offered, more reliably, with better price and delivery, at higher quality, with guarantees over the content and processes.
