"At the same time we also have large numbers of people who pay no taxes, 51%. So as our population grows, the demand for services increases but the percentage of tax paying citizens is not increasing."

By large number of people who pay no taxes, I assume you are referring to working age adults? In other words you exclude those under 18 years age, most college students, retirees, people with major disabilities, those who choose to stay at home to take care of their kids because child care is unaffordable? Also most of those who pay no income taxes still pay sales tax, social security tax, medicare tax and (sometimes) property taxes.
