BECAUSE THEY ARE! Problem?
It would depend on which metamorphic rock. Slate is in demand as a high-end roofing product and paver stone. Marble is used in sculpture, countertops, and flooring. Anthracite is considered the premier coal type. Most rocks, in fact, have some sort of economic usefulness; some more than others.
No. Metamorphic rocks can also from front sedimentary rocks and from other metamorphic rocks.

Metamorphic rocks are useful to us because they can provide valuable information about the Earth's history, such as past tectonic events and the conditions under which they formed. They also have various industrial uses, including as building materials, in the production of ceramics, and as decorative stones. Additionally, some metamorphic rocks contain valuable minerals and ores that can be economically significant.
Metamorphic rocks can form from both igneous and sedimentary rocks through the process of heat and pressure, but they are more commonly associated with forming from existing metamorphic or sedimentary rocks. Igneous rocks can indirectly contribute to the formation of metamorphic rocks by heating up and altering surrounding rocks, leading to the formation of new metamorphic rocks.

Rocks formed from high temperature and pressure include metamorphic rocks such as marble, schist, and gneiss. These rocks are created deep within the Earth's crust through the transformation of existing rock types under intense heat and pressure conditions.
Unakite rocks are metamorphic rocks formed from the alteration of igneous rocks. They are typically composed of pink feldspar, green epidote, and clear quartz.
