The joke of the screenshat xeet was that if your ceilings look like that, you are too poor to be affected by Biden’s tax increases on the rich.

If you are living in a trailer, you are also too poor to be affected by Biden’s tax increases on the rich.

So, the change from “but” to “and” wasn’t to disparage you or your home; It was to clarify that you have two indicators that both point to you not needing to worry about Biden’s tax plan, and given that context “and” is more appropriate than “but”.

An example sentence where “but” would have made sense would be:

My apartment ceilings look like that, but it’s the tenants that I’m gouging that live there. The ceilings of my three mansions don’t look like that, and so I DO need to “worry” about my taxes increasing.
