I have, on numerous occasions, noted how the musing of Megan “Math is Hard” McArdle have at best a passing relationship to the facts.

In yet another example, let me point you to a detailed and thoroughly amusing Fisking of her latest drivel on Social Security:

With even mainstream Democrats coming to embrace the idea of expanding Social Security to help address our looming retirement crisis, it couldn’t be long before the pushback emerged from conservatives and Republicans.

Bloomberg’s libertarian economics columnist Megan McArdle was quick out of the box, with a column published Tuesday titled, “The Left Gets it Wrong About Social Security.” You should read it, because it’s rare to find so much sophistry, misunderstanding and misinformation about Social Security packed into one article. You can count McArdle’s disdain for retired people, seldom expressed so openly, as a dividend.

Read the rest.

It methodically takes apart her assumptions, and shows how they have nothing to do with reality.
