Also, sadly, your statement about that lifehack not working in the US for the good reasons you stated will fly out of the window the second anything browner than a mild tan is involved in the process. Same as the rest of the planet
Let's say you're a brand new, fresh guy off the street without a security license. You apply to a security company, and they hire you. They then send you to training to get your license (armed or unarmed). The instructors they use are former police/military who also train concealed carry/OCP spray/taser/basic hand-to-hand combat/basic & advanced gunfighter courses as their main source of income. They have a VERY vested interest in maintaining their integrity and reputation, not just with security companies, but private individuals who say "I wanna learn gunfighter skills and I want a good instructor!", and the NC Private Protective Services Board has to license them to become Trainers in the first place.
The odds are
very bleak that a group of jeets will somehow become licensed instructors since you
NEED to at least have a year of Law Enforcement or security experience*, and the men who are currently Training Officers that have to endorse you so you can apply to get a Trainer Certification aren't going to allow some bobblehead midget jeet to get it. Their usual tactic of subverting the system via infiltration won't work since, well, jeets universally (barring some edge cases) don't join police or military forces.
Sure, maybe a few will manage to JUUGAAD SAAR their way in, and they won't last long at
all because the PPSB doesn't tolerate any bullshit. They're almost as tough as the IRS when it comes to ruining your day if they decide an audit/investigation into misconduct is needed.
So, for any jeets reading this, like it or not, this is not a field you can subvert. These instructors are all in one big Good Old Boys' club, and you're not fucking in it because a huge chunk of these guys served in the same police/military units together and they have solid reputations out here in the civilian world as instructors.
*officially this is the bare minimum. Unofficially, they demand way more. I've never seen or heard of a trainer that wasn't former LEO, former military, or both with some
serious real-world experience like being former SWAT or having combat deployments overseas.
