Back in the day many national awards had youth rates to encourage youth employment.It’s a tough one & can be quite circular. Minimum wage increases cascade across the whole pay structure and have been a key driver of cost pressure for companies & subsequently price increases for goods & services. Rather than an attack on the poor I see it as part of a broader attempt to moderate inflation.
From time to time I have employed young guys to labour for me. If they can't work as fast as I can doing physical work, I warn them, then sack them. I'm a pensioner with a semi fucked body so no excuse.
