There are two kinds of people: those who escape work or are incapable for it, and those who work fairly (but may still be poor). Former are going to build a lot of bad fences, for $7.25, but business only want latter ones. And if you have Basic Jobs, they would indeed be working for $8.50 in poverty, but if you have Basic Income, those would be working for an equivalent of $7.25 from BI and everything their fence-needing employer can conjure on top of that, which will hopefully give them something around $15/hour, which might let them get out of poverty actually. Low-end labour supply is poor people. Low-end labour supply is people you pay not enough money for them to escape poverty. Any effective fight with poverty would involve disrupting the "low-end labour supply" as we know it today.
