Kidless workers do have some more tax burden. If you presume that taxes are wisely spent, and some of it on education, equal tax payments result in unequal benefit. Not complaining, Just explaining. I live in a country that has decent, tax funded, public education; I understand you may not. But as a kidless tax payer, I fully support decent public education paid for with my tax contributions. I don't think tax should be used as a punishment, especially not since some people can't have kids, it's not their fault.
