Wishful thinking is not idealism. It is self-indulgence at best and self-exaltation at worst. In either case, it is usually at the expense of others. In other words, it is the opposite of idealism.

The most politically painless way to hand out goodies, without taking responsibility for their costs, is to pass a law saying that somebody else must provide those goodies at their expense, while the politicians take credit for generosity and compassion.

Intellect is not wisdom.

Lofty talk about 'social justice' or 'fairness' boils down to greatly expanded powers for politicians, since those pretty words have no concrete definition. They are a blank check for creating disparities in power that dwarf disparities in income - and are far more dangerous.

It is so easy to be wrong-and to persist in being wrong-when the costs of being wrong are paid by others.

Many people believe in eliminating gaps and eliminating poverty. They don't realize that in some sense those two things are antithetical. If you were to double everyone's income, or if everyone's income were doubled naturally over the course of time, then you would reduce poverty significantly but you would have also increased the gap.

The government is indeed an institution, but "the market" is nothing more than an option for each individual to chose among numerous existing institutions, or to fashion new arrangements suited to his own situation and taste.
