But what has destroyed America is liberalism. And liberals come from all socio-economic levels.

Yup. If you read the entirety of the article he's actually talking about Upper Middle Class Liberals. Who support all sorts of thing that kill the economy for their economic lessers, but fight like Rottweilers to preserve their turf and benefits.

So basically the old "Volvo Democrat/Champagne Socialist" crowd. But the writer (a self-proclaimed "Conservative") paints with way too broad of a brush and it comes across a straight up class envy/class warfare rather than the more nuanced class + ideology.

What the author is driving at is that today’s Liberals are interested in feathering their own nests at the expense of the rest of us, be they poorer or richer. He writes that they use the levers of government to pull the drawbridge up behind them. He bemoans that these upper middle class types, they exist, have contempt for the free market. The article also points out that many people have poor reading comprehension or just cannot be bothered to read the article before commenting. Those people think the headline is sufficient.
