I agree.
So what, to a liberal, is government's proper role?
Representing the welfare of the society on behalf of the people, able to stand up to powerful interests who want to excessively further their own interests against the people.
That means things like having policies under which the people prosper the most - tax policies that result in a prosperous society, enough but not too much inequality, etc.
The government facilitates a strong economy - so that productive activities are encouraged and rewarded while harmful ones are discouraged or prohobited.
Sometimes that means getting out of the way, other times intervening. The discussion is more difficult because of the warped nature of activity since Reagan's shifts.
It also means protecting individual rights, from abuses by private forces or the government.
In short, there are two basic models - the high concentration of wealth with a few rich and powerful and the masses serving them in relative poverty, or a strong middle class.
Liberals are for the strong middle class, the doing well by as many as possible.
Freedom, prosperity, peace are the goals of the liberal government.
The liberal recognizes the danger of private tyrrany, not only public tyrrany like the right. Liberals are not anti-well off, they're anti-robber baron rich hurting the public.
