It is very difficult to get 100% halal food in the world. Most of foods are not purely halal as (1) the manufacturer use interest fund (2) ingredients might have prok or alcohol are technically used giving different code (3) manufacturers do not have employees who are practicing Muslims and they slaughtered animals not in the name of Allah (4) companies do not pay zakat at every year end.

How do you think, are we eating 100% halal food always. I do not think so!

This is in general, not for any specific person:

There are ways for people who want to live in that guidelines:

1)Stay in one's own country.
2)Prepare foods on your own.

If one cannot do the above, because he or she does not have plenty of money, then it is better not to show resentment. Many people come to U.S. due to MAINLY money. Once they come, then they start to be picky. They forget or unable to realize "what controls what".
