The human brain is not fully formed until the age of twenty-six. Unfortunately, many decisions that can effect someone for the rest of his/her life are made before then. Many people under the age of twenty-six simply lack the intellectual capacity to project into the future. They are impulsive and want immediate satisfaction. To them, "long-term" is a season watching The Bachelor.
The "acceptance" of tatts, body mods, etc. entirely depends upon both the local social culture and/or business culture. Unfortunately, there is a tendency for people, especially on the coasts, to think of the United States as being this one, big cultural monolith. In reality, it's nothing of the sort. In fact, there can be huge cultural differences from one town to the next in the same state (for example, Austin versus San Antonio; Miami versus Tallahassee.)
Likewise, certain industries have entirely different cultural norms. Being covered head to toe in tatts and ornamental hardware might be perfectly acceptable in the worlds of, say, big tech or certain hospitality businesses. But in the perpetually conservative worlds of, say, finance, economics, or advanced medicine? No chance.
