Tom, I'm sorry that this has just become apparent to you, but this has been the very purpose of a startup since the term was coined. Best case scenario for a startup is to spark a totally new niche and find a totally new audience, but this is rare. Most startups just end up replacing brick and mortar businesses of old and eating their paying customer base. This is economics at its finest, and most definitely leads to a poor outcome for the businesses which are cannibalized.
Labeling people as "good" and "bad" is a futile exercise. Capitalism is a mad scramble to extract wealth from everyone else as fast as possible, with whatever means necessary. To do this lawfully, you usually need to provide some value to paying customers. However, many businesses do it by simply convincing customers that they are receiving value, and do very well (e.g. Zynga).
From the tone of your article, it appears you have just understood that this system will lead to severe wealth inequality spanning orders of magnitude. This is again, a perfectly well understood outcome of the system. The societal and moral ramifications have been largely ignored due to the imbalance of power between owners of capital and those without. Thus, to have a say in the game, one must play it, and become very successful (i.e. a billionaire). In the process of becoming a billionaire, you will find that your views on this matter will change very rapidly in tandem with your net worth. Before you know it, you are advocating for less capital gains tax, more free trade and reduced government. You will see those Occupy Wall St. protesters as pathetic hooligans and low lives, who simply lack the motivation and willpower to make something of themselves. You will petition congress to protect your business interests, and pay handsomely to do so. You will support politicians who maintain order and those who crack down fiercely on all forms of business which are in direct competition to your own. If you are a film industry exec, you will lobby very hard (with SOPA and PIPA, perhaps) against new distribution channels such as Megavideo, Piratebay, etc. which give content away without due royalties. You will be apathetic to anyone who does not understand how this world works, particularly those with low or no net worth who have no say in these important decisions.
Welcome to the game of life. There are very few winners, and most people are losers. The only salvation for the losers is ignorance; to understand the game is to hate it. There is only one other way...play, and win.
