> The chart (2012) is from Gary Alexander, Pennsylvania’s Secretary of Public Welfare - so take note the commenters who are trying to suggest this is libertarian propaganda.

In fairness, the linked image is sourced to a libertarian's blog and Gary Alexander is also a conservative who was appointed to Corbett's administration and was often criticized for extensive cuts to Pennsylvania’s welfare programs which he characterized as fighting fraud and waste until he resigned after a few scandals (https://www.washingtonexaminer.com/politics/2380594/ex-penns...) including the fact that he was still living in Rhode Island and was charging tax payers for his travel/commute expenses.

It is not: it's inspired by it.

If you look carefully, the numbers are different. In Gary's picture, the cliff is from $29k to $69k or so; the one above is much wider.

(It is funny though, the picture above seems to be very much from a serious libertarian.)

Does their political philosophy category make their argument more or less legitimate in some way?

Emotionally, yes. Rationally, no.
