I disagree with that. I’m not a conservative, but I agree with Eisenhower who said “the American mind at its best is both liberal and conservative.” Let’s not confuse conservatism with corporatism.
That’s a relatively recent development, however. The Republican party was not always like this, even in my lifetime. There are high minded conservative values as well as high minded liberal ones. Both parties used to adhere to them more.
Conservatives tend to emphasize more of America has done right & progressives tend to emphasize more of what America has done wrong. The higher truth lies in realizing both: loving our ideals and possibilities enough to be brutally honest with ourselves about what has gone wrong.
American capitalism has become more focused on short-term profit over the last few decades, and in some cases that’s appropriate. What’s inappropriate is their undue financial influence on government, which should always be thinking and acting in favor of long-term societal good.
We need a political agenda based not on corporate imperatives of short-term profit but on moral imperatives of long-term good. And we need to be people wise enough and strong enough to turn it into political force.
