Am I stuck up just for wanting the best?

Okay myself and a family member both have daughters age 4. My family member's husband is a well a no body, he does nothing for a living, (she has a desk job at a trucking company), My husband is a Sgt. in the Army. She recently enrolled her daughter into a goverment funded pre-school, my daughter's pre-school is $340 a month. She want's me to put my child into the "government" pre-school so that they can be together. I however am not going to. Okay a lot of you are NOT going to agree with my reasoning and that's fine but here it is, children in government funded daycare's/pre-schools, have a higher precent of lice, as well as the common cold because parents take their children even when they are sick, many of the children there are from low cl families and tend not to have nice things, where as my daughter has very nice expensive clothes and other things, I chose not to put her in the free pre-school because I feel that since we can afford to give her the very best, that we should (NO we do not give into her if we are in a store and she askes for something and we say no, she puts it back on the shelf not another word is said). In ways I feel like my daughter is better then those kids (most parents feel their child is better though). Plus at her pre-school there are only 8 children to a cl so there's more one on one, an it's not a play all day place, they follow a very strick scheduele through the day, which includes letters, numbers, colors, shapes, learning to spell their names, tieing their shoes, speach, and saftey (learning mom and dads name and how to talk to a police man if they are ever in trouble). I tried to nicely explain to her that because we can afford to pay for preschool we are going to. She called me and my family a bunch of stuck up snobs and hasnt said a word to me since. Now it's causing a rift in the rest of my family. Am I really stuck up for wanting the best for my child?
