Rhetorically that is a widely-supported position on that sub. Actually ideologically coherent/conscious neoliberals tend to get downvoted when they weigh in with ideologically consistent talking points

Its pretty typical Democratic Party doublespeak though. The typical user on that sub will agree with both the statements "A healthy liberal society requires robust social safety nets" and "a healthy liberal society requires free markets and a balanced budget" and will not see a contradiction.
