Could cause some problems for both taxpayers that are involved in this matter.
until the child is 18
It depends on a couple of things. If you still live with your parents, if your parents support you, and if you will be paying the credit bills. Usually if it says household income, it is everyone who lives with you (not including children obviously)
Parents can get an income by working, in the same way that all other people find an income. While it can sometimes be harder to find work that fits in with the care of children, there is always a way of generating an income of some sort. In most states and countries, people who work but still have a limited income are supported with state aid that supplements earned income.
Parents may not able to provide the necessity of their children.
The Head Start program is a child development program that is geared for those with low income. To enroll a child one must fill out an application and return the first page to a local office. One will have to provide proof of income in order to qualify.
What happens when domestic income rises?
Generally no. Parents are jointly liable for their children - i.e., one parent's income doesn't excuse the other parent.
higher income levels for parents aren't related to the intelligence scores of their children
Yes. There is no exception to taxes on account of age. The child must file their own tax return (obviously if the child is too young, the parents can fill it out for them). The child's income cannot be combined on the parents' return (unless the child is subject to the kiddie tax and the child's ONLY source of income is interest and dividends).
Parents need to earn money so that they can care properly for their children. It does not matter what particular job they do, but they need one which pays reasonably well. When the children grow up they should follow the good example which has been set by their parents. When they have left education they should try to "pay their way" with their parents by contributing part of their income to increase the family's income pot. When their parents are older and retired, the younger ones should help to care for them in return for their parents' years of child care.
Child labor in a way is very bad but when we think of those poor children whose parents are not able to generate so much of income to support their family.Here child labor becomes a good thing as the small child is able to generate some income for his family and act as a helping hand for his parents.
Sometimes, yes. But this largely depends on the state laws, as well as the income of both parents.
