We could curtail private spending by several trillion dollars a year without requiring painful sacrifices from anyone. That would be more than enough to rebuild our crumbling infrastructure and eliminate government indebtedness once and for all.

No one could argue with a straight face that the couples getting married today are much happier just because their wedding celebrations cost three times as much as those in 1980. Bigger mansions and costlier parties are wasteful in the same sense that larger antlers on all bull elk are wasteful. The good news is that simple changes in the tax system can eliminate much of this waste without having to deny people the right to decide for themselves how best to spend their money.

Rising inequality hasn't really accomplished anything of value for its ostensible beneficiaries, the top one percent. They've all built bigger mansions and staged more lavish parties. But in so doing, they've simply raised the bar that defines what's considered adequate in these categories.

When the economic pie grows larger, it's always possible for everyone to have a larger slice than before. So it's really in all of our interest to make the economic pie larger by eliminating waste whenever and wherever possible.

We've long known that firms can pay higher wages if they spend less on workplace safety enhancement. Libertarians ask, "If a worker is willing to accept higher wages in return for his agreement to exercise greater caution while performing his job, why should the government prevent him from making that choice?" It's a rhetorically powerful question, yet it overlooks the fact that the agreement in question will have adverse effects on others.

Pass down values every day through your actions, your words and your time with your kids.

The fact that many private expenditures are mutually offsetting actually happens to constitute a remarkably good bit of fiscal news. Mutually offsetting spending patterns are wasteful in the same way that military arms races are. In such situations, if each party spends less, nothing is sacrificed, yet resources are freed up that can be put to much better uses.
