Are you referring to "forward trading" or "online trading"? It is a good communist slogan to blame trading for inflation. However, any examination of this problem will show that trading, including forward trading, has a moderating effect on markets.
If you want to avoid all this, it is best to scrap all markets and install a Soviet-style Stalinist government. The question is, will it work in this day and age and do people have the stomach for it.
