Wow where have I heard this one before? Nobody knows what's going to happen in the future, 100 years ago probably nobody could predict the industries that have arisen today just like we can't predict what's going to happen in the future, when you say machines are going to take over the jobs, yes maybe the ones today but that's because we're becoming more productive and as humans advance new industries start to form. Those who anticipate where the new demand will be are the ones who start it off, the Bill Gates and Steve Jobs of the world, extraordinary humans unlike you and I, so just because you can't think of where the jobs are gonna come from in the future doesn't mean there aren't gonna be any because if you did know where the jobs were gonna come from you'd probably become very rich.
A lot of people here need to read Economics in One Lesson by Henry Hazlitt
Now money, on the other hand... Money is an abstraction, a placeholder. Without money, we barter, my goods or services for yours. With money, we still barter, but we do it in half transactions. I give you my goods or services, but I don't want what you have to sell, so you give me an IOU, money. Later, I complete that trade by redeeming my IOU for something that I do want. Because money is an abstraction, in the aggregate, holding money is akin to having provided goods or services, to the world. The money that you hold represents capital that the world owes you, but can use until you call for it.
Thank you for that. I never thought of it that way, but it makes perfect sense, and fits nicely with the point that wealthy people, who aren't thieves, are only wealthy because they gave something that the people of the world wanted or needed.
This is essentially why free markets are the best, because greedy people have to find a way to help people to make money
