I didn't ask to be born. No one does. When my parents had me they had to assume the responsibility of taking care of me and the costs that went along with it. In return, they didn't expect anything. The tide is turned and now I'm a mother. I have a daughter who I provide for. I'll teach her the best I can and how to manage money when the time comes.
She's not my retirement plan. I didn't have her so that she could care for me in my old age. It's not tit for tat, I take care of her and she takes care of me. That's simply not how it works. However, for some people, it is. Some families believe in having more kids so that they can support them. I've even heard parents telling their grown kids that since they had to feed and clothe them for 18, 20, or more years, they have to do the same. I found that in Peru, grown adults often had to provide for their retired parents. I speak Spanish and had no qualms giving my opinion. If you don't speak Spanish, now's the time to learn. It'll help you assimilate to the culture,and you'll be able to communicate easier. If you're looking to learn Spanish, check out Synergy Spanish, Rosetta Stone, and Fluent in 3 Months.
That's wrong and it's not fair. People need to plan and organize their own finances. They need to budget and save. You need to have a variety of options available: stocks, bonds, CDs, mutual funds, saving accounts, property, etc. Not kids. Kids should not factor into your retirement planning. Research shows that it costs over a quarter million dollars to raise a kid from birth to age 18. If you really want to save money then don't have kids. It's as simple as that.
