Problems with Common Good
Value Systems
People cannot agree on āthe good lifeā. Our relative values differ too much
āFree-rider problemā
Certain groups of people will not do their part and exploit the common good for their own gain. E.g. Tax evader still partakes in free healthcare
Individualism
Self interest prevents people from willingly sacrificing their freedom for sake of the common good
Unequal Burden Sharing
Certain groups must bear greater costs. Rich will pay more taxes of course.
