Suburbs cannot function without freeways, but the presence of freeways harm the property values of city neighborhoods not suburban ones.
SFH simply produces less tax revenue than an entire apartment building by land, so any statewide social services (education, freeway maintenance...) is paid proportionately more by cities than by SFH.
There are reports[0] of cities reporting that their SFH actually loses them money due to the fact they simply don't pay their fair share of taxes vs all the infrastructure they use.
It's not like the government is going "oh boy, SFH mom, here's 500$ plucked straight from some inner city mom's payroll taxes". But in the broader system of supporting many people's living styles through greater societal infrastructure, less-dense housing like suburbs do not put out as much as they take.
