Do supporters of illegal aliens use facts or emotions on this issue?

I just believe they do care what happens to this country. Not concern about what will be going on in 10 years or what kind of future they are leaving their kids. I still want to ask why is Calif broke ? Why is Calif facing water shortages ? LA has everything the supporters of illegals want, but it doesn't seem to be doing very well.Nobody can tell me illegals live in shadows in LA ,so why so many problems in LA ?
