The chief cause of this intense strain is the uncertainty attending the operations of Wall street. The chances there are not dependent upon the skill or the exertions of the operator. Some powerful clique may almost destroy the securities upon which he relies for success, or may make him wealthy by suddenly running up their value; so that no man who does not confine himself to a strictly legitimate or commission business--and but few do so--can say one week whether he will be a millionaire or a beggar the next. The chances are in favor of the latter result. Nine out of ten who speculate in gold or stocks, lose, especially persons unaccustomed to such operations. Like all gamblers, they are undismayed by their losses, and venture a second time, and a third, and so on. The fascination of stock gambling is equal to that of card gambling, and holds its victims with an iron hand. The only safe rule for those who wish to grow rich is to keep out of Wall street. While one man makes a fortune by a sudden rise in stocks or gold, hundreds lose by an equally sudden fall in the same commodities. Even old and established firms sometimes give way with a crash under these sudden changes. The legitimate operations of the street and the speculative ventures are becoming more and more concentrated every year in the hands of a few operators and capitalists. These move the market as they please, and fill their coffers, and sweep away younger or weaker men with a remorseless hand. It is useless to oppose them. They are masters of the field in every respect, and when they combine for a common object, their resources are inexhaustible and their power beyond computation. A dozen, or even half a dozen of the great capitalists could ruin the whole street were they so disposed, and once they came near doing so. This is the secret of the cordial hatred that is felt by the majority of Wall street men for Vanderbilt, Drew, and other great operators. They know and dread the power of these men, and would readily combine to destroy them singly. The mania for stock gambling which now sways such masses of people, may be said to date from the war and the petroleum discoveries. Since then it has rolled over the country in a vast flood. The telegraph is kept busy all day and all night in sending orders for speculations from people in other States and cities to New York brokers. Everybody who can raise the funds, wishes to try his or her hand at a venture in stocks. Merchants, clergymen, women, professional men, clerks, come here to tempt fortune. Many win; more lose.
