The US is just really inefficient with how our income is utilized. According to this chart I'm around the 90% mark as a sole income earner (my wife doesn't work due to medical issues) and I don't feel very secure. If I was by myself I'd be okay but adding all her expenses really sucks up a majority of what would be my expendable income.

A lot of it really comes down to having no (or unreliable) safety nets. If she was at least getting SSDI that she should be getting then we would be in a much more comfortable position but instead I'm footing the bill for our crappy system.
