Blue collar worker in non-income tax state that doesn't own property and has 2-3 kids is probably going to be around 12-15% overall. That's a pretty small subset of the country, 2-3 states or so. If you use the same book of tricks (i.e. ignore a myriad of local taxes and taxes collected on goods sold) that people around here typically use when trying to make certain high tax states look not too out of line with the national average then huge swaths of the south and midwest would be included.
