See the article "Economic Crises and the European Revolutions of 1848" (Berger and Sporer, 2001):
Recent historical research tends to view the 1848 revolutions in Europe as caused by a surge of radical ideas and by long-term socioeconomic problems. However, many contemporary observers interpreted much of the upheaval as a consequence of short-term economic causes, specifically the serious shortfall in food supply that had shaken large parts of the Continent in 1845–1847, and the subsequent industrial slump. Applying standard quantitative methods to a data set of 27 European countries, we show that it was mainly immediate economic misery, and the fear thereof, that triggered the European revolutions of 1848.
While this doesn't rule out multiple, contradictory dynamics going on at once, it's pretty clear evidence that precarious living standards had an important role.
