Please, the exceedingly wealthy don’t muck out their own barn.
Where I live a piece of equipment like an excavator is a great investment. It’s a tax write off and it frees up time for you to do other more valuable tasks instead of breaking your back with a shovel for far too long.
Many (most) people will take out a loan to purchase a piece of equipment with the expectation that it will “pay for itself” over it’s service life.
Ah yes, the classic trope of the wealthy farmer, mucking out the barn and then checking the time on his Patek Philippe watch. I bet his pigs only drink Voss water.
Yeah, dude got wealthy by mucking shit out of a barn. Pick up a shovel and give it a try -- you too, can get exceedingly wealthy :)
