A parent with two children: A man worked part of the year, earning $9,000. He has custody of two children. He owed no federal income taxes for 2007. He would be eligible for a base rebate of $300 for himself because his earned income was at least $3,000. He would also qualify for a $300 children's bonus for each of his two kids.
Rebate: $900
I'd consider this one a handout, not a rebate. This guy needs a full time job to support his family, not depending on the government to help him.
A couple with two children: Both worked part-time in 2007 and have two children. After taking available deductions and credits, their federal income tax liability was $500 for 2007. Because their earned income was more than $3,000, they would qualify for the $600 base rebate for a couple. They would also have enough earned income to qualify for a children's bonus of $300 for each of the two children.
Rebate: $1,200
Again, how can people with kids work part time?
A couple with five children: After taking available credits and deductions, their 2007 taxable income was $95,000, leaving them with a federal income tax liability of just over $16,600. Under the proposal, they would get the full base amount of $1,200. They would also qualify for a children's bonus of $1,500.
Rebate: $2,700
These people probably don't need the cash. $95k AFTER deductions puts them in six figures, they should be able to survive without any help. 
Retired couple: As a result of their investment income, a retired couple paid $4,000 in federal income taxes in 2007. They had no dependent children, so there is no children's bonus.
Rebate: $1,200
Investment income being enough to be taxable. They are probably living comfortably as well.
A couple with one child: They were able to retire young but still collect dividends and capital gains from a business they sold a few years ago. The couple paid $19,000 in federal income taxes on that income in 2007. They would qualify for the base amount of $1,200. They would also qualify for a children's bonus of $300, because they paid at least $1 of federal income tax in 2007 even though they had no earned income.
Rebate: $1,500
Retired young? With two dependet children. They are not hurting like Average Joe either.
High-income couple with children: Both spouses are lawyers with a combined income in 2007 of $300,000. They have four children. Because their AGI is over $150,000, they are disqualified from receiving either the base amount or the children's bonus.
Rebate: $0
The only formula that does make sense.Please note there are no examples of single taxpayers, single parents that work full time OR of retirees without investment income living off social security.
