With globalization, the domestic market is thrown open to the world. A population which has so far seen the worst of that area ( Best are exported or are much more expensive that what an average household can afford ) is now exposed to the best from each country. Also, globalization ensures that these products are at the best possible prices.
On seeing this plethora of choice, the common man first buys the essentials, then satisfies his needs then completely indulges in his wants.
Better technology and the internet have made this even more possible.
I would definitely agree with the statement that globalization has increased consumption.
