I'm waiting for them to openly acknowledge that everyone can be property.
You own your wife. You own your laborers. You own your slaves. They do not get a right to vote, as they are property, but allow the owner to vote on your behalf.
I predict that essentially white male professionals and the very wealthy will be the only ones permitted to own said property. White male Doctors, lawyers, engineers, scientists, professors, managers, accountants etc. Most of these won't have their own slaves, generally they will "invest" in a wife. Why? Because they are salaried, and typically bring in a stupid amount of money compared to labor.
Consider my job - software engineer. My charge rate is twice my salary broken down into hourly pay. And quite often I have to work more than 40 hours a week - I don't make more, but my employer gets to charge more. Depending on the contracts, this means more pure profit.
Labor will still be paid in the sense that it will be more like the 1800s. Labor does not generate profit by itself (in the owners mind). Labor, therefore, is an expense, and gets treated like property on the employer's time.
In the owners mind, slaves are full property, able to be traded amongst owners. They get the benefit of being fed and being housed. Depending on their value, they may even get limited healthcare.
Women will be property, full stop. Modern educated women will be attritioned out, and young women and children will be indoctrinated that their purpose is to service men, and eventually handed to a suitor to produce children.
I want to admit something here, something gross. That last one is going to be the most difficult to fight. I am even tempted by the idea of it, simply because I'm pretty lonely (to no fault of women, but the nature of my environment). If I'm tempted by it, I am not the only one, and there are far more vulnerable men that are advocating for it.
So the question becomes, what do we do? Well, I think right now we continue to resist, we continue to defy, we continue to push the fascists into infighting.
What happens if we're unable to stop it? I can only hope that current families of women and children are highly selective about partners and continue to see the value in their independence. We don't have to make it easy for fascists to get their way.
I want to note that I didn't mention the LGTBQ+ community. In the MAGA worldview, they don't exist. Existing is a crime. It will be up to those of us who consider ourselves allies to do what we can for them, which means subversive education, which means doctors and pharmacists taking risks, which means living the saying "if you see something, no you didn't. If you know something, no you don't." This is the new culture we need to accelerate. This is vital. Germans and Russians were more than willing to report on their neighbors. We cannot allow this under any circumstances.
TL;DR: don't give them want they want.
