Again, I'm not sure about the situation in the US, but here we have public services that can help people go through debt restructuring or private insolvency in the worst cases, as well as offering classes for money management and centres for addictive behavior. This isn't done purely out of humanitarian concerns either, addiction and lack of education are problems that keep people from being productive citizens - and this is expensive for society at large.
That's not right. We're living in a world like this. When people cite stats that show x% of people living paycheck to paycheck that is almost guaranteed to be due to over-consumption and consumer debt if your household income is above, say, $50-60k/year. At that level, you have over-consume to have nothing left over.

Most of the people struggling are below this figure and not because they spend too much on TVs.
There's a reason why some people get into debt because of consumption: they don't plan reasonably. What do we do? Do we not pay them UBI but give them pocket money and keep the programs in place to cover their rent etc because they can't be trusted to take care of that with money we give them? Do we just ignore their fate and watch them go hungry and eventually homeless? Do we keep the programs in place, give them UBI and then pay their rent when they spend the UBI but didn't include the rent?
