Why is there income – or more precisely wealth – disparity? Why has there always been wealth disparity. Is it because some people are deliberately holding other people back or is it because some people are just lazy? Maybe we can answer those questions with another question: "Where does wealth come from?"
Where does wealth come from? People make it – and those who make it have it and those who don't don't. It's that simple. People make wealth, and in a free republic there's nothing or no one to stop them from doing it. So if you want wealth, get off the couch and go out and make some.
From medieval armorers to Silicon Valley engineers, it has always been individual skill and dedication that produced wealth. There has never been any other source. There simply is no substitute for knowing what you're doing and having the initiative to do it.
Implicit in the wealth disparity indictment is the promise: "... and the government's going to do something about it." But there's nothing, of course, that the government can do about it. Governments do not create wealth – people do. The government can't make a thriving city out of an army fort. Only people can. The government doesn't build houses and factories and banks and department stores and restaurants. People do. The government doesn't build canals and railroads and highways. Only the people can do that. The most the government can ever do is use the people's money to effect the people's wishes.
At least that's what it's supposed to do.
Nor can the government distribute wealth. It can only destroy its creation. The most efficient wealth distribution machine ever invented is the wealth creation machine itself – industrialization. By buying raw materials, by procuring and maintaining plant and equipment, by hiring labor, and by building railroads and highways and pipelines to transport labor, raw materials, and finished goods, the very mechanism that creates wealth effectively and efficiently distributes it to the community.
The government can only get in the way of this well oiled machine – to everyone's detriment.
