Developed countries, through education and economic realities, generally have children at or below the replacement rate. Most of their growth comes from immigration from other countries with much higher birth rates.
The incentives you're talking about are there to stabilize the population so there isn't more people in nursing homes than there are propping up the economy taking care of those people. It's a tough situation, and with the capitalist systems in place and a lack of long promised automation in many industries, it's worrying for everyone involved.
So really it's already working the way you want, largely. If you want something more dramatic you need to find another lever, and at the same time you need to balance your goal with the dropping population in the workforce so you can afford to care for the elderly.
