Landlords and other oligopolistic goods-sellers with a lot of leverage and cartel-like dynamics can now count on a base income for everyone. I don’t see how low income housing doesn’t instantly becomes more expensive across the board, with profits funneled to established landlords.
At least with SNAP/EBT, your landlord can’t take that money.
UBI is sold as a cheap program to run because it eliminates the application and verification processes involved with existing benefits programs. But those same concepts could be applied to existing programs.
Other pro-worker reforms could also replace the whole UBI idea, where UBI just feels like a band-aid for a society with worsening income inequality and increasing corporate control. It has a “fix the symptom” vibe.
