Some people say that their job doesn't pay enough for them to be able to afford childcare. Or, to be more specific, their job doesn't pay enough for them to be able to meet the needs of their family, including childcare costs. Before you make plans to launch a career (and possibly incur the expenses associated with educating yourself for that career), find out which jobs don't pay enough to enable you to support a family (including childcare costs) and avoid those careers!
It's also smart to avoid educational expenses that lead to careers that don't pay enough to enable you to repay student loans if you need them.
The good news is that it's often possible to do something you will enjoy most days, without pursuing low paying jobs. For example, if you love teaching, but fear that being a school teacher won't pay enough to support the lifestyle you desire, consider becoming a corporate trainer which usually pays well. Or if you want to work with children, consider becoming a speech-language pathologist which can involve teaching children outside a traditional classroom.
When people pursue jobs that pay well, in addition to meeting their own needs and enjoying the freedom that comes from some level of financial flexibility, they also help people in low paying jobs by lowering the supply of people pursuing those lower paying jobs. Basic economics teaches us that when supply becomes scarce, wages rise. And wages usually rise faster when supply is reduced than they do by complaining, striking, or attempting to legislate pay rates.
Avoiding future frustrations takes planning and hard work, but it usually pays off in the end.
