The problem is that they don't. What happens is the private sector gets the reward, and the communities bear the risk. What we've seen in our fundamentally unjust system is that, just to look at the pandemic, billionaires have gained $3.9 trillion, and workers have lost $3.7 trillion globally during the pandemic, and this historic transfer of wealth to the 1% is an indictment of this neo-liberal model that privatization is a key part of. More privatization isn't building back better; it's just building back more of the same that got us into these problems in the first place.
