When you find the cure for greed ad power, let the rest of us know.
There are alwyas ways to steal money, I know of no system that can prevent that.
Do you?
Sure do.... the complete removal of currency/money/capitalism all together. If it's not there, then you can't steal it. If you can no longer seek money and personal profit to shape your way of life, then what is next to improve/focus apon?
And no, before someone goes down that path and telling me I am referring to Communism, learn what it actually is first, because I am not even close to referring to Communism, as even Communism had money/currency operating in it's system. It was regulated through the government rather then the people overall, therefore money/capitalism is still existing behind the scenes, AKA: Corruption still existed to a certain level, and not to mention, was partially or mostly the main contributor to why the Soviet Union collapsed in the first place due to the Cold War and Arms Race.
Like the seperation of church and state (or the attempt there of) so too does the removal of currency/money/profit need to be done for any process of government/society to actually work properly. Humanity worked just fine before money/gold pieces/etc. it can work without it again. It's a system of keeping track of trade which has become overly corrupted and outdated and the moment we all realize that it is and we need change, the sooner we can remove the problem which you presented.
Greed and the want for power may still exist, but think about what is the main contributing factor in what drives someone's greed and desire for profit/power? Where does it all root to?
Now, when looking at the main difficulties which are in many relationships around the world or just the average person's own life, one of the main contributing factors to relationships ending, divorces, stress and family disputes over funerals, etc.... are all usually related to money in one manner or another. Not being able to afford the basic requirements of the household, someone spending more money then you are saving, someone's medical bills, someone's education bills/tuitions, it all boils back down to money/capitalism.
We're all trying to ride the same game and get ahead of the next person to make us feel we're better off or in a better position/status in life over the next family or person. We are basically pitted against our own species in a survival of the fittest, when we should be working together as a species. This system in itself is geared to keep humanity as a whole seperated and devided against one another, so that the select few can make it out on top.
Capitalism doesn't help Democracy, Communism, Socialism or any other system. Capitalism only helps Capitalism and the select few who are willing to step over your fellow man to get more of it.
Sometimes the most simplest answer is the best solution.
