Immigration
5
The biggest issue of our generation because unprecendented mass immigration from poor countries is hitting every developed, advanced nation in the world (Japan being a possible exception). France, the UK, Australia, the U.S. and just about any place you'd want to live is being hit with waves of persons coming from the 3rd world.
Immigration is commonly fine. However, problems arise when the newcomers have little interest in assimilating or subscribing to/abiding by the values of the host country.
If you think near unrestricted immigration is "OK" for people who are seeking to escape poverty, come visit Los Angeles. In fact, you don't have to do that. Just jump on the internet and take a look at what Californians score on public school tests, the rate at which they graduate high school, the traffic they have to deal with, what they have to pay for homes in an area where there isn't enough housing, and the increasing taxes that citizens must endure.
It's no joke folks. Get informed. Your childrens' futures depend on it.
