1) Efficiency concerns: decentralized allocation of capital versus political allocation of capital
2) Business cycle concerns: raising taxes in a recession was one of the things done during the Great Depression, and there's a reason it lasted 12 years.
3) Fairness concerns: The rich already give about half their income to government (depending on the state and the method by which they earn their income). How much is too much?
4) Revenue concerns: the income of the rich is highly volatile, and so is the revenue of a country that depends on heavily progressive taxation.
5) Long term economic growth concerns: Capital is more mobile than ever, and people will prefer to invest in countries with lower taxes, ceteris paribus.
6) The Laffer Curve: it has an inflection point.
I'm not saying the anti-taxers are right, but any honest commentator should acknowledge that some arguments exist on the other side. But in Krugman's world, people only disagree with him because of personality flaws (angry, selfish, myopic, stupid, etc.). I can't stand the man's smug self-righteousness which he keeps regardless of how mainstream or controversial his opinion on the topic at hand. The man sold his soul to democratic socialism a long time ago to the point he pretends that no other valid worldview exists.
I can't think of a single economics columnist who is more partisan or who treats his opponents with less regard.
In particular, this article scans like a college newspaper op-ed. It is a simple Rah Rah piece for his side. It could have been written by a campus Marxist group. "Look at the poor rich folks, struggling to pay for their private schools and limosines". Gosh Mr. Krugman, with such incisive commentary I can see why you got that Nobel.
And of course he forgets to mention that most rich people vote Democrat, so his entire argument that the rich are "angry" is questionable to start with.
> most rich people vote Democrat, so his entire argument [...] is questionable to start with.
Not even close to correct. Gender, age and state of residence are good proxies for voting patterns, but none is better than wealth/income. The rich, as a class, support republican candidates. The basic rule is that rich states vote Democrat, rich people vote Republican.
Keep in mind that I am merely stating that an argument exists, an not making it per se. I am questioning Krugman's rhetorical strategy of assuming that no reasonable disagreement exists.
The only data I can find puts people making over $125,000 as 46% Democrat and 51% Republican in 2004[1]. Of course, this was before the banner Democratic years of 2006 and 2008 when Barack Obama beat McCain in campaign contributions 3 to 1 among employees of large Wall Street banks.
So you're right, it more even than I thought. Rich people probably went Democrat in 2008 and may swing Republican again in what is shaping up to be a huge year for team GOP.

The authors of the book Red State, Blue State have all the data you need to answer this question, and they helpfully blog various tidbits and state breakdowns on various issues like this.
While the couple earning that in the Bay Area may be doing it hard, the difference between that and the lifestyle of the poor is immense.
There is a fairly thick layer (my bet is at least 35% of the population) of middle class people between your Californians on $125k and hopelessly hardscrabble folk on the breadline.
Edit: it looks like it might be a little higher percentage, actually, if we extrapolate from old data from the 2000 census http://ccsre.stanford.edu/reports/report_13.pdf
I'm pretty sure among you and Krugman, you're a hack.
I'd be hard-pressed (as would you) to concoct a "poor" person's tax return with an average rate of roughly 30-40%.
