Stan Shunpike and class distinction

Do all British wizarding children go to Hogwarts?  What about Stan 
Shunpike?  If he's 18 or 19 in PoA, mightn't he have been there for 
Harry's first year (if he went)?  Are there major class distinctions 
in the WW?  Are there some children whose families can't afford 
Hogwarts, and where do they go?  Do all British children wear 
uniforms at school or is that just at elite boarding schools?  How do 
the Creeveys support two students on a milkman's wages?  Is there a 
scholarship program?  Does anyone else think of this stuff?
