Nothing is free in life.
Public school education may seem “free” but you are paying for it with your taxes. When the economy is doing well, and you are making a lot of money, then schools will get more funding.
If you have an incompetent president, like Barack Obama, and the economy does worse (16 million more American citizens entered the poverty line under President Obama!), then public schools get less funding.
Having more and more illegals storming America with their children taxes the public school system in America, making them inferior and worse.
More and more illegals entering America hurts immigrants who entered America legally and American citizens and their children, who will necessarily receive inferior education.
Real enemies of children of illegals are Democrat politicians and extremist “Progressive” leaders who keep pushing illegal immigration in America, which encourages more and more people to make a long journey of tears to enter America, illegally (which ultimately hurts America’s public school education!)
Aggressively Marxist Progressive leaders like Randi Weingarten is driving America down by encouraging illegal immigration and compelling many poor families to make the long journey that may end up in their children sold into sex trafficing and child slavery.
Many illegals do not reach America and end up selling their children or themselves for sex prostitution and for a form of sex slavery.
Democrat leaders who push illegal immigration are potentiating rising sex slavery among poor people in Latin America, who end up into sex slaves in their illegal journey North.
