Hello good-karma..
Honesty does not look at the size or the size of something. Being an honest person is a must for everyone. If your parents work with honesty, then you should be proud of them. Although it is small, but a blessing, even if it is a little, with blessing and halal label has been embedded in it. So that makes it very enough for life.
God never sees a person from his wealth, from his work, or from his physical form, in the eyes of all men the same. What distinguishes us from other human beings is Faith and Piety. When you are present in life with the role of being "small", but with faith, piety and good morals will disregard any destructive whispers in the course of your life. Get rid of all the prestige of those who waddle with their wealth, start is trying and still help and respect your parents in searching for lawful halal. Because nothing is worth shaming as long as you fight for something kosher.
