Define robbery. Taking the US as an illustrative example legalising corruption in politics through Citizens United, the government subsequently effectively pumping investors portfolios with the poor's money through QE, and then proceeding to raise taxes on the poor by not adjusting brackets for inflation all not robbery because there's this veneer of legitimacy and legality and two parties you can vote for that will do the same thing? All justified by the too big to fall doctrine that simply the bankruptcy of the wealthy is apocalyptic but the bankruptcy of the poor does not matter? Lets not also mention Exxon making record profits by getting government subsidies and further subsidising its own profits by making the world poorer with its pollution

In any case, the economics of the world are a totally unsustainable and inefficient concentrating of wealth which will eventually cause consumerism and the engine of world economics to collapse blowing up the entire wealth pyramid. On top of these economic issues, global warming and the fact that oil demand seems to be plateauing (So we can't kick the true costs of energy down the road) is suddenly going to make being poor much more expensive. So regardless of who is robbing who, at some point sheer practicality will prevail and redistribution to the poor will need to happen (people can call this robbery if it makes them feel better), and if it doesn't happen voluntarily, it is likely to result in an eventual revolution.
