The current tax system is weird. If you're poor it's pretty straightforward. If you're middle-class you get hit by weird rules that don't make sense and can end paying a lot of taxes. Some examples are international tax rules and AMT on stock options. When you get very wealthy (IE net worth >25M is required for good wealth/tax management) you end up paying very little taxes.

I'd prefer real solutions to the tax system instead of applying more duct-tape to it.

The same for the climate plans. Any real solution requires an efficient carbon pricing market. Instead we get a subsidy on all electric cars other than Tesla.
