What are positive rights?
Are there also "negative" rights?
So-called "positive rights" are claims upon things to which one is supposedly entitled, and which are required to be supplied by others if one lacks them. If others do not supply such a thing, then they may be coerced into doing so (in order that your "right" to that thing is not violated). Examples of positive rights include the rights to food, housing, health care, education, a "living wage", etc.
So-called "negative rights" are claims upon things to which one is supposedly entitled, but which are
not required to be supplied by others if one lacks them. If others do not supply such a thing, then they may
not be coerced into doing so. Examples of negative rights include the rights to free speech and to keep and bear arms. (Your right to free speech does not require anyone to give you a soapbox if you don't have one, and your right to keep and bear arms does not require anyone to give you guns if don't have any.)
IMO, it would be better to refer to "negative rights" as "liberties" rather than as "rights"
[1]. That is, it would be better to say that people have the "liberty of free speech" (or to keep and bear arms, or so on) rather than to say that they have the "right to free speech" (or to keep and bear arms, or so on). This is because the concept of "rights" evolved in the context of things to which individuals are (or are not) entitled. Outside the context of voluntary contractual obligations, the concept of rights was easy to hijack by the "positive rights" crowd. If they had to speak in terms of things like a "liberty of education" (instead of a "right to education"), they'd be less able to get away with their rhetorical shenanigans. Speaking of a "liberty of education" does not seem to imply an involuntary obligation by anyone to provide an education to someone else -but speaking of a "right to education"
does seem to imply such an obligation (or can easily be construed to do so).
[1] At same time, "positive rights" would just be called "rights", and would only arise from voluntary contractual obligations. For example, if I agree to buy your car for $1000, and you give me your car, then you have a (positive) right to get $1000 from me.
