Access to good wholesome and healthy food and water already is and will be based upon a families financial situation. The traders have nothing to do with this.
Even in developed countries its only the rich that can afford to pay the higher price for organic chemical and pesticide free products or afford to buy a house in the mountains with good clean well water. The poor eat much worse and drink flouridated and chlorinated water from municipal water treatment plants.
The earth and it's weather are changing and top soil is being lost at record paces. Water to grow crops is often scarce and expensive. Also it's important to understand that governments are often the cause of higher prices in commodities. There are countless crazy deals, laws, and regulations that inflate prices. This happens all over the world even in America. Do a little research on the insanity that has been going on in the US sugar market. The sugar cartel and their lobbyist have artificially inflated the price with the help of the US government. Once you start investigating and researching, it's quite obvious that placing the blame on individual futures traders is like blaming the dog for the rain. The same corruption, lobbying, and nasty deals that make the sugar cartel rich in the video below happens with ALL COMMODITIES, not just sugar. The big commercials form cartels and invest huge amounts of money wining - dining and bribing politicians. The end result is always higher prices for the consumers and processors.
When it comes to futures markets, the ignorant finger pointers don't have any idea of the real market forces and blindly blame to individual traders. Far far more damage is done by the legalized fraud the big commercials and bankers commit. Then there's the elephant in the room of HFT. Talk about artificially inflating prices, there's nothing that comes close to the damage being done by these algo's. High frequency trading accounts for more that 50% of all trades on the equity markets, and I think its much higher in the less regulated forex and futures markets.
Compare all this to your retail futures trader who rarely if ever holds a position overnight. In other words, he may sell, but he buys it right back before the day is over. No net position and no real effect on price. You can argue that he takes the price up when he buys a few contracts, but then he also takes it right back down when he sells those same contracts a few hours later. It's a wash.
To get an idea of what has been going on in the sugar industry and likewise with ALL COMMODITIES I highly recommend the following video:
