what enables us citizens to consume a disproportionatley large amount of products compared to the rest of the world

The US citizens consume a disproportionally large amount of products compared to the rest of the world because of the high spending power of the population and extremely easy availability of products.

Explanation:

There is a large disparity from country to country when it comes to the number of products consumed by their respective populations. There are many reasons for this, but the main ones are the spending power of the population and the availability of products. The US citizens have both of these factors at a top-level.

The US is the biggest economy in the world, so the amount of products on the market is incredibly high and diverse, not to mention relatively cheap. The population has relatively high earnings, so the spending power is high. With the infrastructure being on the top level and the advancements in technology, everything has become even easier, so the US citizens consume a lot, not just how much they need, but actually much more than they need. The estimates are that the US households actually throw away anywhere between 30 and 70% of the food they buy.
