I agree to, what happens when you decide you no longer like the idea of having ear gauges? What happens to the look of the ear?
I think the same thing about tattooing to, sure they now have laser removal if you decide you don't like a tattoo, but that leaves a scar. If a person has a small tattoo that can hide under a shirt, fine, but those people that get tattoos all over their head, neck, down the arms and hands etc is just crazy.
I also think the same thing about cutting, those scars never go away.
And most employers, who are usually middle to older age people, don't want a ear gauged, body tattooed, scarred up, piercing all over person to work for them, especially higher paying employers. Discrimination you scream, sure, but the bottom line is you represent the company and if that representation is negative then that can ruin the reputation of a company. Some companies don't care, like bars, motorcycle shops, welding companies, factories etc usually don't have a problem, but being a national sales person, doctor, lawyer, a teacher, etc...forget about it.
I understand the right of a person to express their right to do with their body any way they see fit, I get that, but don't become bitter at the "establishment" when you didn't get hired for a lucrative job and feel like you were discriminated against, all companies have a certain idea of what is acceptable in the appearance of their employees be it clothing or body art, and they have to right to have that expectation, it's their company not yours!
