What you say is true to a point. Computers do change the playing field, and in the securities market it has made it very possible for people to trade all the time, creating a benefit to certain savvy persons with the bucks to play the game in an advantageous fashion.
But there is also a lot of people who once upon a time wouldn't get involved in finacial matters that make outrageous decisions. I have some in-laws in my extended family that bought real estate in Florida at the height of the boom, and got clipped big time. I looked at some of the properties they bought, one in particular, and I couldn't believe that they paid that much money for such a place. I said little to them" "yeap, it looks like you paid a bit too much." When in reality they paid way, way too much. They bought one condo for 590K that is only a little more than 1,000 Sq. Ft., and then, they were offered 400K almost two years later, which was still too much. Now, they cannot even get a bid. They are the kind of people who sit in front of a computer' pay for financial advice via newsletters and software packages, etc, when they should just stick their money in the bank and forget it.
On the other hand, for example, computerized bookkeeping, which is what I do for a living, has reduced the cost of keeping books by 80%. Of course, some people don't know what they are doing, or think they can hire a 10/12 dollars an hour person to do the work. I had a customer that took me nearly six months to fix the mess and then file three late years of income tax returns. By the time they finished paying the IRS, they wished they had hired a professional.
