The lady neighbour with the cookies...
Apparently, she doesn't know how jobs work. Yes, the 'neighbourhood paid for your addition'. People earn money by selling goods and services to others in their communities. It's called a marketplace. That's how EVERYONE makes money.
She talks as though there was no value in what he'd sold them - as though they were forced to buy something that doesn't work, where in fact they depended on this day more than any other on his product, which they obviously judged worth buying.
It's maybe the stupidest accusation ever recorded in a movie.
