GAW,
Good question. Since the question was what they deserve, I would say current normal. B”H most are willing to live at a standard below that, and unfortunately, many are forced to live at standards considerably lower than that.
Since what we’re talking about is subjective, I’ll give an example.
Essentially, someone involved in avodas hakodesh should receive our utmost respect, and deserve to dive a Lexus. However, this would be distasteful, because someone in avodas hakodesh is expected to be above such pursuit of gashmius.
Wouldn’t it be nice, though, if our klei kodesh were able to drive a relatively late model, respectable looking vehicle, to fit his family in comfort, and not be busy every week at the mechanic?
Unfortunately, though, too many must drive an old, beat up jalopy with barely enough room, and constantly getting it repaired just to get it into working order.
Unfrtunately
