Such opportunist people are not helping the cause for which others are protesting.
Apples and orangesSame thing happened in Pakistan in 2007 after Bhutto assassination. Has nothing to do with materialism. Looters and criminals exist everywhere not just Western countries. Education system in US being messed up is also a contributing factor.
Unless you own a target or a cheesecake factory, the looting shouldn't really be an issue for you. Most of these companies exploit their workers and do far more harm to their community than any "harm" that these corporations are suffering via "looting".
