They should spend some of their SkillsFuture credits on upgrading courses. Perhaps they can upgrade to become blind masseurs, which pay more than blind tissue peddlers.
I could, but I would need to charge them. That's what their skills future credits are for. I already have a partnership with companies that provide such courses. It's a good source of defensive revenue. Business for my skills upgrading gig has improved a lot thanks to covid even as my food catering main business has been badly affected.
