Nowhere in that essay, which distorts the Pope's remarks, does it quite Francis as saying "capitalism is evil." Francis routinely points out the problems that occur when we give too much power to the wealth that capitalism helps produce, and in this he is no different from his predecessors, one of whom cut his teeth running underground churches under communist oppression. The flaws of capitalism are pretty clear to anyone who doesn't idolize the system - and the Church never has. Rather, she recognizes that any approach to life that does not put Jesus at the center will ultimately bear poisonous fruit. The goods of Capitalism are subordinate to Jesus, the ultimate good.
Capitalism is a tool and like any tool its use can have evil results. Some of these results have been the treatment of people as disposable means rather than uniquely valuable ends. You can admire the material benefits of capitalism while remaining uneasy about these clear problems.
