OCU:
Times have changed. We already have a mature population of over 300 million, and we don't need additional low-skilled immigrants (unless you're keen on driving down wages and crippling workers' ability to defend themselves in the market). It becomes so difficult to do social and economic planning for the difficult years ahead without having a good handle and limits on our people, their needs, and their skills.
Now with insolvency, gross distribution of wealth, mandatory austerity, and Scumbags controlling our country on the very near horizon, let's defend our people, not bring in more souls that we can't properly cope with.
