Child care is expensive and very time consuming. In America where more and more families requiring two working adults to support itself, it's getting even harder.

Could the workforce be made more productive with government aid for childcare for families where both parents are working full time jobs (or more) or single parent families where the parent works a full time job? Is there anything already like this? And don't say 'school,' because despite the childcare nature of schools in the US, they don't go for as long hours as most parents work these days. I'm not calling for government-run facilities (more like something like school vouchers? I dunno), just making it more affordable.

I know this is kind of out of place considering the US's current multitude of problems, but I'm curious.
