Capitalism is based on the theory of evolution and works by the same basic principles as natural selection. Socialism is based on artificial selection, which is why is tends to implode after a period of time.
For example, Apple came up with the iPad a decade ago. This, in terms of a parallel to the theory of evolution, is a genetic mutation or a natural change into a new life form. This mutation represented change; new critter, but that along did not mean it will automatically succeed. It still has to compete, to see if it has selective advantages and be subject to natural selection; high consumer demand. Only then will it persist.
If it does, which it did, it begins to breed and spread; supply increases. Like life, it can never rest on its laurels, but has to constantly evolve, improve and adapt, to maintain its place in the eco-system. Capitalism is organic, while organic is not always pretty. The lion will kill the gazelle, which gets messy, but this assures the lion's and gazelle species survival. Other similar competitors will also try to move in on the territory. This brings out the best in all, and efficiency improves even further, to meet the challenges of our rival; Eye of Tiger.
Socialism is more based on artificial selection. In this system, bureaucrats decide which cattle it wishes to breed. It does not wish to let nature run its course in free market. This artificial choice may not based on natural potential such as fitness and utility. It can be based on cosmetic reasons, or even career and monetary payoffs. This choice is also due to layman bureaucrats and politicians making decision even about complex specialty areas beyond there skills. What do lawyers know about heath care? Why would one expect them to pick natural selection winners?
In natural selection, it is the experts; mutations/inventors, who drive the innovation. They help make the choices. Apple depends on its inventors, innovators and marketing people to assure mutations have fitness in the jungle, before the mutations appear in numbers to compete. You can't go wrong if you use nature as a template, since this has worked for a billion years.
The problem the left has it prefers artificial selection, based on appeasing insecurities. If people are afraid or insecure, the quick fix is what they want. However, natural future fitness is based on the ability to adapt to the unknown and not just the known. In the free market, they need to anticipate all types of potential future problems, from supply chain, to changing technology to new products. You approach can't be too fixed in time; quick fix fad, or else you will go extinct. This long term planning step always plagues Socialism since it does not think, as does nature.
