The earth connector does not prevent electricution however with a RCD the power can be cut before serious damage can be done. Where they do not use an earth then to get electricuted you have to make a circuit with your body between live an neutral i.e. hold live in one hand and neutral in the other for example. There is no chance of electricution from metal appliance surrounds connected to live if you do not have an earth it is only if you are stupid enough to make yourself part of the live neural circuit.
Having an earth actually creates new dangers and only with an RCD are to really safe, add in that electronic decoupling makes for leakage to earth anyway then having an earth is considered, by many, to be more hassle than it is worth.Hence why most other countries electrical systems do not bother.
