The trade off for that is that you get very long periods of fitness for use, where you can comfortably buy something that is advertised for a purpose and know that you can return it after a reasonable time if it isn't actually fit for that purpose. A good example is smartphones and laptops, where Australian-sold iphones effectively have a two year warranty and macbooks have a three year one iirc because of these strong consumer protection laws.
It's these kinds of faulty goods returns to smaller retailers that I've had most trouble with in the US (and where I think consumer protection makes the most sense). In Australia the consumer would simply file a complaint online to the Department of Fair Trading (or whatever it is for their state) and these are usually resolved within a couple of weeks or less and usually in the consumer's favour. I'm not aware of any equivalent in the US, and if it does exist I'm sure it varies significantly state-to-state.
