It's not easy to raise a family, especially in todays economic climate. The cost of living continues to rise, while pay rarely increases. With that being said, I think we're at a point where both parents have to have a job in order to survive, and it will only continue to be this way unless changes are made to our economy.
Cost of living is costing people to also stop having kids. Some young adults are opting out of having children as it's too costly these days. The stress for them, isn't worth it. And the sad truth, is I think things will only get worse, to the point we see an decrease in birth rate.
The financial burden of raising a family, isn't worth it to the youth these days, so I think we're going to see a rise in childless marriages.
