You have got to be joking.
Firstly, look at the bigger picture. If the 55k comes from a single wage earner the income tax before deductions, not including medicare levy etc is over $9000. They are paying $25 a year in flood levy alone. Oh and $4900 or so in superannuation because we can't let people chuck $320 into their dental health now, but at least they can buy dentures with their super. Why would we make someone like that pay ten THOUSAND dollars in tax then worry about how they can find $320 for dental work. If we started encouraging individual thrift perhaps we could let people make their own decisions about how much to spend on teeth with their own money rather than churning and churning.
But secondly, maybe I'm harsh but I absolutely think average wage earners should be able to find $360 (like I did on $55,000) for something as important as dental hygiene instead of expecting some massive government program?? When I think about this I just can't understand what the future holds for a society like ours...with these attitudes I'm not surprised we owe 250 billion...the more I think about it the more bizarre it seems to me.
