Aff seems like a good k aff. I have been reading on this subject and i have noticed that the sex trade is actually good for the economy in Cuba. You'll need a way around how by stopping sex trade, you are hurting the economy. What I suggest you do for this and for a topicality for not econ engagement is say we are topical because we are engaging in cuba's economy except we are creating a negative effect on it by stopping slave trade (because the topic only asks for economic engagement, it doesn't specify whether it has to benefit or hurt the economy you are engaging in). A lot of teams might just run some type econ disad against you, but you with still outweigh because you would solve for sex trade which would have a deontological impact (dehumanization). There are tons of cards out there saying why you outweigh because you solve for sex trade even for one person. I actually have a human trafficking advantage for my aff so you can pm if you need some stuff for your aff. But you have to look into if the cuban embargo might limit your solvency or actually be used against you as a no-solvency argument.
