his point was that all the time the wealthy man wasted on becoming wealthy could have been spent learning, if he just worked enough to support his family
This ignores inherited wealth. The rich man may have spent no time becoming wealthy.
As good part of my practice is as a trust administrator. Some beneficiaries receive a hefty monthly income, never having to work, great grandpa or great grandma may have done that.
As for the fancy walls and trimmings, the late Mrs. CTL was a designer builder realtor. Our home was larger and fancier than our needs, but it housed her office and served as her showroom and portfolio (almost like living over the store in generations gone by). Her potential and return clientele expected as much.
The Litvish Yeshivish system seems to approve of women working and men learning.
By the time her estate is settled, there will be grandchildren living in or owning fancy decorated dwellings for which they did not have to sacrifice an hour of learning to work in order to acquire them.
I don’t pretend to know more than a Gadol, but his observations about a specific situation in a different place and time should not be applied by others who don’t know other people’s actual circumstances.
