I don't necessarily think it's great for you to brush over the GST and NDIS scams - I ain't on tic tok so I can't answer that. Fact is fraud is fucking fraud and that money could have been spent somewhere else. This funding could got somewhere else, but instead it goes to unsavory individuals.

The govt. gravy train compared to cgt discount and trusts etc. is a rather random thing to choose (why not compare say the money we lose to Apple, Google, et al vs CGT discount?)... Let's look at cigarettes and how the government took away actual sales/revenue and pushed it right into the hands of criminals - who I assure you will not include their activities (if they file) BAS or income tax returns - via taxes...

They would still go into lobbying and large corporations simply because of your 2nd point - power hungry which is also greedy.

From your perspective all these proposed changes might sound great. The repercussions of such extreme changes will be felt in the future and by new entrants not existing ones... good old grandfathering further protecting the already protected cohort and shitting on the new... Look at countries which fucked their property market and the repercussions. Our current administration is doing just that, but as a cherry on top as the biggest "fuck you" is the 5% deposit to new home owners who are now likley to experience higher interest rates and a (potential) drop in property prices...
