Let me translate this thought process from rich asshole to regular human:

• People need roommates because they cannot afford to live on their own.
• The reason they cannot afford to live on their own is because they aren't working enough hours (to make him more money.
• The reason they aren't working enough hours is because they have to spend too much time engaged in activities that aren't work.
• A robot frees them of having to do things that aren't work.
• Thefore a domestic robot will make his workers do more work and achieve their purpose of working and paying all their bills.
