In reality that makes getting a license - any license - in the first place a much harder ordeal, and it means that the contractor has to learn extremely location-specific knowledge for places they won't be working just to prove they can work anywhere in the country. This is despite the likely outcome that they'll disregard 90% of that information later because it's not necessary to know in their region, making that study a waste of time. This is not grand and results in the exact opposite of what we want to achieve.

• A: It'd drive up licensing costs.
• B: More study time would be required just to pass, and the fail rate would be higher.
• C: The customer would have to pay more to cover the professional's increased licensing costs OR businesses would absorb losses/simply fail.
• D: Professions that are already understaffed would be even more so, damaging the economy in various ways. Those jobs exist because somebody needs them done >!(more true of a concrete layer than a cosmetologist though)!<.

Because I think criticism is a poor substitute for offering solutions, here's an alternative:

• Certifications for general knowledge in a profession should be nationalised, whereas location-specific knowledge should be localised. This in practice should mean that you don't have to re-do your whole license again when you move state, but you do a two or three week course that gets you up to speed with a particular type of soil/weather condition/set of local regulations.

... Of course not. A subconscious brain picks up visual signals that indicate another person is fearful, and reacts accordingly - all without conscious input.

There is no "communication", let alone telepathic communication. It's just people using their eyes and brains.
