rarer these days.
Actually, though, roads are a public service, older than the Roman emperors. Schools are maintained by every kind of government system, socialist states just one of them, and predate socialism as a national ideology. Critically, socialism requires collective ownership and control of the means of production.
Now, if his farm and others around belonged to a collective that was either self governing or controlled by fairly local government, and he worked for and was part of that collective, that'd probably be considered democratic socialism. (The democratic part would be they'd still have democratic elections.) If the farm collective was under the authority of a central government, say back in DC or the state capitol, that'd be more like ordinary basic socialism.
Btw, collective ownership of America's farms would be virtually guaranteed under socialism and very possible under dem soc. Back in the 1970s-80s, Sanders advocated a long list of means of production that should be seized for collective ownership. Just looked and unfortunately couldn't find it; it's been awhile. But farms are basic production, food supply after all. To put it mildly, he made few converts back then, and when he entered congress his made his list very short instead.
These days it's so short that he's telling people roads and schools are socialism and people are really already socialists. NO, and I don't know why he's saying that, but people who are interested should go find out what socialism is and is not for themselves. Not from a proselytizer or politician either.
