Would you have rather grown up with everything you could have ever asked for (that money could buy) or with out most things you desired (that money could buy)?
By buying it yourself you have a greater sense of accomplishment and self-pride. Also, you don't grow up an entitled douchebag.
When you have nothing you become more creative. I thought our family was dirt poor until I was about 15. Turns out my parents were anything but & I truly appreciate just because I actually value my hard work & what I earn from it.
