I do not want to directly oppose some of the misguided views here but I see a lot of hatred for HFT, finance etc but at a very basic level there should be no regulation or hindrance for 2 ppl to exchange value (trade) as long as they believe they are deriving some value out of the transaction they are being part of even if others believe that the transaction is of no benefit (after all who can decide what's of benefit or not).. The idea of trade (any form of trade or barter) from an individual perspective is not for the betterment of society but for their own good but the unintended consequence is advantageous to society as a whole..
People might hate globalisation, free flow of capital etc but there is no denying that the onslaught of globalisation has reduced global poverty but I agree this has been at the price of increased inequality... Increased inequality in my opinion is better than all being equally poor... And for ppl who would disagree that global poverty has reduced just check world bank data on all statistics such as nutrition, health care, life span, access to electricity, telecommunication etc and you will see all there has been a remarkable rise in these factor over the last 30 years all over the world...
