The electric charge of macroscopic bodies is actually a surplus or defieciency of electrons. Why not protons?

We often say that the net charge of macroscopic bodies is basically deficiency or excess of electrons. Why not of protons ?

An electric charge on a body produces

Electric charge on a body at rest produces

When we mention the charge of body we indicate only the deficit or excess of electrons in it but not protons. Why?

The ratio of specific charge of an electron to that of a protons is
