The target of any government should be the production of reasonable, not excessive, levels of wealth from durable products.

By experimenting in weightlessness, scientists can better understand the processes involved and learn to improve on them, to create stronger, more durable products such as aircraft engines and spacecraft.

Rubber injection molding process produces a high yield of durable products, making it the most efficient and cost-effective method of molding.

In general, durable products and housing are very illiquid assets because of asymmetric information (information on their quality can be very non-transparent).

Consumers will then be less reluctant to purchase durable products and spend on residential and housing assets.
