I've found that whenever I've shared my ideas with friends or family, they default to poking holes in them. Instead of looking for reasons why it could work they start listing obvious problems that I've already considered. Things like "You would have to get insurance" or my personal favorite "if it were that easy then everyone would be doing it." Because of this, I learned long ago not to share any of my projects or ideas with anyone.
The flip-side is that when I started to have some success, those same people who would always be so negative became angry with me. After his first time visiting my new home one guy even picked a fistfight with me and I've picked up that several family members have been running me down behind my back.
Many working-class people are prone to envy but at the same time they underestimate their own potential. It's best not to worry about them.
