Since metal is a resource that can be recycled over and over again without loss of quality, recycled materials are as useful to manufacturers and builders as freshly extracted and forged metals. Thanks to the unique feature of this element, collecting scrap metal for profit is a common and sometimes profitable task. The scrap metal business is more reliable than other industries. It's not like selling high-end hot tubs or speedboats, things that people would like to have, but that they can't always afford to buy when the economy collapses.
The scrap industry has existed for generations and will continue to grow as demand for recycled metal products increases. Right now, due to the increase in construction and industry in countries around the world, the prices of scrap metal such as copper, aluminum and steel are much higher than in previous years. Earnings are for enjoyment, quality of life and success. Scrapping metal seems difficult and dirty, but that's the charm of a niche industry with wide profit margins.
In reality, scrapping is and will always be aimed at maximizing profits, like any good business.
