A lot of these things seem like complaints about reality rather than complaints about the way society is organized. I'm sure there's some social bias against single people in the workplace and out. That seems like a reasonable complaint. On the other hand smaller food packages, for example, require more packaging material, more shipping weight per portion, some fixed organizational overhead per item, etc. Two people sharing a bedroom, kitchen and a bathroom is always going to be more cost efficient than one person in the same bedroom, kitchen and bathroom. Two people sharing a car is more efficient than two single people each buying their own. A family phone plan is more efficient to manage cost-wise for a phone provider since they only need to manage one account.
