[Just mythoughts]

I didn't know that carpenters in classical Roman times were extremely wealthy.

Joseph of Arimathea, Christ's uncle was a wealthy tin miner. It was Joseph's tomb, never used before where Christ was laid after His death on the cross. We are told little about where Christ was and went prior to His last three + years of life in a flesh body.

You're inserting late, late medieval legend into the ancient 1st century accounts. If Joseph of Arimathea was a wealthy tin miner it is not known to history, nor is there any reason to suspect he was. Same goes for that "Christ's uncle" business.
