I'd say they're entitled to their opinion. But that's all it is, an opinion. By all objective measures, the economy is improving,
even if some don't see it.
But, if you want to claim that Biden's policies specifically contributed to any economic problems, you need to provide evidence. Specifically, exactly which policies impacted the economy in what specific way to directly cause the adverse outcome.
Otherwise, it's entirely possible the reason for the problem (whatever it may be) is something else entirely. Like repercussions of the pandemic, for example, or corporate profits increasing due to higher prices that don't come down when the costs do. Or Trump. Or space pixies. Who knows?
Without facts to back them up, any number of conclusions can be assumed.
