He obviously should have just had one kid and then this wouldn't be an issue. I don't see why people struggle to see how the additional taxes could be a burden on many. There are net benefits for many as well. Demonizing people that would be adversely impacted, like unable to afford their mortgage, by the greater taxes is unfair though
The costs of having a family and a mortgage and whatnot would be, to an extent, offset by the programs these taxes are intended to fund. This isn't a situation where you look at that chart and extrapolate that you'll be whatever number you see in the hole.
Also, I'd hope that wages would start increasing soon, given the inevitable raise to the minimum and the fact that employers are no longer doing us the great service of providing relatively affordable health insurance as a benefit. I would hope that people these days aren't too shy to argue that the complete disappearance of the employer-to-employee compensation of health insurance should be made up through some other means (ideally through wages).
