personally ive become less happy about it as time goes on
my main gripes are the erosion of cultures, mainly due to the world being addicts of american media
but also economic as it makes different countries too reliant on other countries, which sucks because those other governments arent elected by your country
If you think about it a bit, I think you can see that the bad effects of what is often called globalization also happens on a smaller scale inside countries, often with homegrown organizations/companies being the culprits. IMHO the underlaying problem is not globalization per se but rather that large monopolistic companies can use the power imbalance to take over local & foreign markets and push their one-size-fits-all products and cultural marketing onto people regardless of their wishes.
In a sense these large conglomerates are only piggybacking on a generally good trend of global economic interconnectivity that has brought a lot of positive development in the last decades.
