Liberals believe Government has two moral missions:
to protect and empower everyone equally.
"
The means is The Public, which provides infrastructure, public education, and regulations to maximize health, protection and justice, a sustainable environment, systems for information and transportation, and so forth.
The Public is necessary for The Private, especially private enterprise, which relies on all of the above.
"The liberal market economy maximizes overall freedom by serving public needs: providing needed products at reasonable prices for reasonable profits, paying workers fairly and treating them well, and serving the communities to which they belong.
In short, 'the people the economy is supposed to serve' are ordinary citizens. This has been the basis of American democracy from the beginning."
Conservatives stand this on its head with their worship of all things rich and rancid. (like Romney)
