SOME MAIN PONIT:

It is clear that political actions influence an interdepant world economy and shape the world. Particularly, it has coheration relationship. I mean, with this relationship, globalization is the best way to raise incomes, promote the long term developmenr of the world's poorest economics.
For example:
 - Wages is improved => Living condition is higher
 - Poverty is diminshed
- Everyone has own opportunities of success
- Globalization tie us together and creat a connectedness among people
 
In contrast,
Polarization is happened . This means globalization also make people reject outiside influence and see it as underming their values and be danger to their cultural legacy => Many countries have reacted with anger and alienation to the cultural influences of US or a leveling of cultural values.
