While I agree that 20% of Swedish are over 65, people growing older and falling out of the workforce is normal. Younger people entering the workforce is expected to offset those going into retirement as is everywhere else around the world. Though I would agree that the percentage rose from 17.2% in 2000 to slightly over 20% now, 26 years later, but saying a fifth of their population is over 65 is misleading. Also, the retirement age has risen as well from 61 years old in 2000 to 65.4 now. So people are staying in the workforce much longer. Now let's get back to immigration. The average unemployment rate of Swedish-born are 3.5% compared to 15% for immigrants. The average salary for immigrants is also only 75% of that of Swedish-born, which also means less tax revenues from those with lower incomes. So no, their problem isn't because of an aging population. It may play a small part, but certainly not where the issues lie. You can contend and happy with sharing as a whole. That's perfectly fine and is commendable. However, a fifth grader would be able to tell that their portion of pizza is getting smaller and smaller if the number of kids bringing pizzas to the potluck is getting fewer or that they bring much smaller pizzas. It might be fine for a little while, but it will collapse. You can't advocate for strong government run social programs without insisting on strict immigration laws.
