I'm on mobile now, so I'll try to be as concise as possible... while the Risorgimento was carried on mostly by the upper strata of the population (however, the garibaldini were also aided by the local, and landless, peasants during their conquest of Sicily) there were certainly effects on the lower classes as well.
Internal trade barriers were taken down and with them, the need of a passport to travel within the other pre-unitarian entities (such as the Papal States); but in some cases - e.g., the South - the results of such trade liberalisation were controversial. This also meant that some taxes, like the one on flour, were applied to places which did not historically levy them (such as the former Two Sicilies) and this led to frequent revolts.
Local laws, as well as the states' customary measures, were repealed in order to be replaced with Piedmontese legislation (and the metric system). A partial exception was Tuscany: the death penalty was in force throughout the Kingdom except for that region, where it had already been abolished in 1786. However, the new country's laws were finally standardised in 1889 with the adoption of the new Civil and Penal Codes which, among the other things, abolished capital punishment (which would be back in force again from 1931 to 1947) and decriminalised homosexuality for the first time in our history.
North-Eastern Italians, which had been under Austrian domination from 1797 to 1859/66, did certainly welcome the absence of a strong censorship apparatus as well as the depart of those Austrian-appointed bureaucrats which had monopolised the local administration at the expense of the local notables.
Attempts were made to redistribute lands among Southern labourers (the latifundus was still alive and well down there) but the local landowners managed to block any such proposal; a serious land reform saw the light of the day only in 1951. So, the situation did not improve much for the Southerners and in some cases it did actually worsene.
Mandatory schooling, which Piedmont had established in 1859 thanks to the so-called legge Casati, was extended to the whole peninsula; and for the first time, Italian ceased to be a (mainly) literary language.
