I had a client's kid the other day who is a construction worker, his wife's in college and they have a child.
The American Opportunity Tax Credit wiped out the tax liability. Then between the refundable portion of the AOTC, the additional child tax credit and the earned income tax credit, they ended up getting about $3,000 more back than they had paid in. On roughly ~$37k AGI. They aren't gaming the system or shaping their lives for tax credits, just playing by the rules your elected officials put in place.
But no one who thinks these credits are a good thing should ever utter a word about any of the credits businesses get. At least most of the time those are tied to something most people would agree should be incentivized (as opposed to incentivizing being poor and having children).
And along that same line, "tax breaks for corporate jets" is one of the most ignorant damn things a person can say. Just know, if someone says that, they are just parroting what they've heard on the news and have no idea what the hell they're talking about.
