I guess the first thing I would say is this. Some people say, well, $10,000; who can afford to put money in there if you don't have a lot to begin with? For really wealthy people, they're not looking at vehicles like the TFSA. That is not something on their radar in terms of investments.
I remember distinctly when this change was.... I got a call from a supporter in the GTA. She and her husband were new Canadians. They had been using the TFSA. She said her household income, with her husband, was around $40,000. She said they had been able to almost max out their TFSA every year. I said, “That's very impressive. I don't think the average person would think you could save that much.” She said it was a key part of their retirement plan, precisely for the reasons Mr. Brain mentioned—namely, in terms of the money you put in there, whatever accumulates is tax-free.
When you ask how we reduce poverty, remember, we're not just talking about people today, we're talking about poverty in the future.
