For the best commentary on current events, I turn to Page Smith's People's History of the United States, published in 1976.
When it comes to education, for example, we now know what Thomas Jefferson suspected- that talent is distributed evenly among the populace without regard to race, sex, or color. The society that does not provide a universal free education is simply wasting a certain amount of the talent that society already possesses.
Liberalism might help its own cause if it could state clearly such a basic economic principle before going on to talk about how good you'll feel if you help others. Heaven knows, the idea is hardly new and it's been tested and proven by time.
Look homeward, angel.
