He's wrong, there is no Ponzi scheme at all. Let me explain...<p>First of all, we have limited resources. The resources we absolutely need, for example, food and water, however, exist in enough quantity for all the people that currently exist (otherwise they would die).<p>The second layer of resources, for example, metal to build cars, crude oil for energy, also exist in enough quantity <i>for now</i>.<p>The exchange between basic needs and not-so-basic needs is irrelevant of the price that we are actually paying for them, because there is enough for everyone.<p>So the economy is built on the most important part of all - human labour. When I program, I expend labour, and though nothing gets added or removed from the world, I can still exchange the time I spent for a basic need like food.<p>This debt he is talking about is debt of human labour, and even if you wipe it out completely, the worst that has happened is that people wasted their time, and they will not get paid for it. There is no real destruction of the most basic needs.<p>If for example, we were destroying farmland to produce in excess right now, and we know this will make the farmland completely useless in the future, then this is a scheme that will collapse. But we're not doing that in any significant quantity.<p>Furthemore, we don't need to conserve things that are not finished yet. For example, let's imagine that we are going to run out of iron in 100 years. Obviously, this will be problematic, but 10 years before it happens, the price of iron is going to skyrocket, because we know of the impending scarcity. And there are lots of materials we can use to replace iron. Same with oil.<p>There is no ponzi scheme. People are paying for an easier life, and they are paying other people to make life easier for them.
