fat belly politicians pension

Why is that an average pensioner gets their pension cut for having an investment property and if that property is over 820,000 dollars they do not get any pension at all? Whilst our fat belly politicians who have retired get a 6 figure pension no matter how much their investments are worth. This is costing the tax payer more than 40 million dollars a year. So someone that was a tax payer that payed for this can no longer get looked after by the government. Is this fair? No no no to cutting the average pension.
