They have less income to spend. This has mostly negative consequences. Lower economic stimulation is the most obvious. Of course, less income means other things too. Young men are living at home with their parents for longer, or in flophouse conditions. At least in the US, this is not a desirable quality to most females, meaning they are getting married later if at all. This means less children, which could mean a demographic crisis depending on which camp you believe. Also these people could be an eventual drain on society as they get older or retire.
