Lars is a tax guy. This has been a good skill for him. He likes it, kind of a math-like career foundation that makes him useful, earns him a good living, and has forced him (he recognizes) to develop people skills in order for things to go well. He's gotten more interested in estate planning and estate taxes in recent years, but income taxes have been his bread and butter for most of his career.
What Congress did at the beginning of January is an interesting combination of income taxes and estate planning stuff. It's mostly good for those who are wealthy or want to get there. There is still a favorable tax rate for capital gains (generally a maximum of 20%, compared with 39.6% on ordinary income), and the lower rate was also maintained for qualifying dividends. Of course there is policy justification for taxing dividends at lower rates; theoretically at least the corporation's income has already been taxed. But it's still a good deal for those who have stocks, like Lars. His portfolio will grow a little faster over time as a result.
