1. There are very, very few life-long partnerships. And of the ones that are, some of them are for reciprocal benefits (not love); some are because the people are too scared or complacent to leave; some are because the two are completely lacking in ambition and hope for a better future. Most people change over time, and most people change differently (especially different sexes). To imagine them remaining on a parallel trajectory through long life by nature (instead of sheer willpower or complacency) is naive.
2. Swiping left/right by looks is not for long term partnership. It is for short term physical excitement. And in that regard, it's a good start.
3. No amount of online communication or friend referrals will compare to frequently being around someone, getting to know them, and falling in love with them. This is a very low percentage game he's betting on (unless he's just betting on publicity, in which case he wins 15 minutes of fame).
4. Wait until the (unnamed nationality) recruiters get wind of this. For a chance of $7000, they will inundate him with dates. The smartest of them will promise to share half of it with the women, in which case he'll have more dates than he has time for. And if he has some money, the more desperate women will fake their way to marriage, winning the $3500 and potentially a comfortable life (only having to have sex with him a couple of times per week).
This may sound pessimistic, but it's really just an observation on traditional modern marriage. People don't work like the story books suggest, and the story books are based on fiction that doesn't represent the vast majority of human history.
The good news for him and anyone else who wants to expand their awareness is that one can have many good meaningful relationships and some really great physical relationships in one lifetime. And be happy through most of it.
