Why don't I ever hear Latino illegals being thankful for all the things America has given them?

I mean the attitude is so disrespectful we didn't ask for them,,they aren't doing us any favors America is a nation of humane principles and we extend a loving arm to the needy and turn a blind eye to the law in the name of Human Rights,,,where do they get off thinking they are being cheated and mistreated,,,,and why do they think that America is a endless pit of money and prosperity,,,It is not,,it could fall quicker than anyone thinks if we adopt the values of these illegals,is it possibly they will ever see their wrong,,,I FEAR NOT
