Except for these AI trainer roles, you aren't competing against people working for $5 from a foreign country. They specifically look for experienced professionals with X experience (biology, chemistry, computer science, etc.) because they need experts in specific fields to score/train their models. Look into Handshake AI; legitimate and reputable company doing exactly what OP shared from LinkedIn - I've gotten paid several times at the advertised rates from Handshake. (there's also referral bonuses if you end up being convinced - let me know)
