The situation you're referring to, where older citizens own more assets than average, might indeed seem obvious in Canada but it might not be the case at all in any country with a differently structured social security system, since the decision to save money for a rainy day or not is directly affected by the availability of social security. In a country with an ageing population and with a pension system overwhelmingly funded by intergenerational transfer, then voting for tax cuts is optimal for young voters. In a country where pensions are mostly funded by private savings, then sure, taxes are nice.
