We can't prevent suffering. Cooperative systems like all sorts of communism don't work because people are by nature lazy and even worse greedy. Everyone maximizes their needs and minimizes their abilities. Hence we are left with competitive systems like contemporary capitalism where pressure to perform and be better than the others directly leads to suffering as inevitably there will be losers. The winners also don't fare much better as well. It is often a Pyrrhic victory. Cursed if you do. Cursed if you don't. And in the end to feel better about ourselves, we the society, tell people it is worth living so they do their stressful job for a few more decades and enjoy a few weeks of free time a week to play Candy Crush on their iPhones they are still paying via installments. But even if looked beyond politics and social organisation perfect prevention of suffering is impossible until medicine reaches some state of seamless merging with (bio)robotics. Ironically the competitive pressure might actually be the way we reach such a state of science. Ray Kurzweil is talking a bit about this in the book about the Singularity.
