- America will have its first female president
It's way too early to say anything at all about 2020, but I'm hoping for Kamala Harris. Sadly there's a significant contingent who would rather vote for a serial killer who openly campaigns on using the powers of the office to feed him several daily victims than a woman, so who really knows.
- the wagegap will be reversed. Men will earn less than women on average.
If current trends continue, it actually might, assuming you cut out the top few percent of wealth from the calculations... though it will probably take longer than 10 years. The qualified pool of middle-class job employees favors women, especially white women, slightly at present, but they don't get hired or promoted at the same rate as men yet. If there's a continued trend of women getting advanced degrees at a higher rate than men, then we can't expect sexism trumping qualifications to hold it back forever. Meanwhile, short of drastic social and economic changes, the top ranks of society will heavily and unfairly favor men for decades to come.
- prostitution will be illegal in the Western world
It's already technically illegal in most places, though not always strongly enforced. My prediction is that the US will trade the drug war for a trafficking war which focuses almost entirely on sex trafficking... and backfire horribly, making it far more prevalent and profitable in the process. Meanwhile independent sex workers will take nearly all of the damage which supposedly isn't even aimed at them. Most of the rest of the Western World will not go there (though there will be a few emulators) and a few other countries will take steps to legalize it instead.
- third world countries will get invaded by horny white men looking for wives, leading to 3rd world women becoming just as hypergamous as Western women. (this has probably already happened, but it will get even worse in the future)
Ignoring that the very concept of "hypergamy" is questionable, this is something which has always happened to a very limited extent ever since international travel became available to people who aren't wealthy. I'm not convinced that it's happening any more than it used to, we're just hearing about it more.
- men will need to fill out applications that have to be approved by the government to travel to 3rd world countries
What? No.
- misogyny will be a punishable crime. There will be severe censorship against anything woman hating.
More like, there will be increasing amounts of no-platforming, which is censorship in the social sense but not in the legal sense. You will be penalized in various ways for being openly misogynistic outside of small, radicalized bubbles... but that's not the same as going to prison. However, there's also a growing intolerance of misandry as well. Not the weird nonsense which misogynists *think* is misandry, but actual real misandry. So it will go both ways.
- open cuckold relationships will be the norm and not the exception
Poly relationships probably still won't be the norm, but being open about one's poly relationship probably will be. I don't think that will be true of cuckolding, however. Based on my admittedly limited knowledge of it, that kind of thing probably generally works best as a "dirty little secret". I doubt incels would understand the difference, though.
- bachelor tax
Already sort of exists in places which offset the marriage penalty in their tax code, depending on how you look at it. If you mean taxes meant to specifically punish people for not getting married, people have been griping about that possibility for well over a century, and there's no evidence such a thing is imminent. If anything, the usual reasoning behind it makes even less sense in the present day.
