There's always someone trying to spin capitalism problems into government problems. No, taxes are not the cause of inequality. If nothing, taxes are one of the few tools we have to reduce it.
Lol no they aren't. Taxes do not get used, they get burnt. The government does not budget based on taxes. They just spend whatever they are going to spend. Taxes are used to target specific inflation. This way they can keep everyone on the treadmill. Taxes are for the poor and working class, not the rich. You will not be able to convince the rich and powerful to tax themselves in any meaningful way.
This is absolutely not true for most countries; not everyone can just increase their debt mindlessly like the US does. My country, for example, has a budget and taxes make 90% of it. That means if we get more money through taxes, we can spend more on healthcare, education, infrastructure, etc.
Controlling inflation is also a good thing for most people, as higher prices will impact the consumers and the poorer parts of society. Ensuring abundant supply would be a better way to do it than reducing demand, of course.
