The free-marketeer response is that many of those problems have actually been caused by a lack of adherence to capitalist/free-market principles - eg. a policy of bailing out banks since Continental Illinois, preventing market discipline and leading to riskier behavior; heavy involvement of public policy distorting markets (both through laws pushing cheap housing mortgages, and through government-sponsored institution like Fannie Mae); land expropriations in China that force people to accept those slavery-like jobs (obviously not in accordance to strong property rights as defended by free-marketers); government-granted monopolies (including patents), and many more.
