This is a tax on the company. This is not a direct tax on workers. A flat tax on people I agree is bad policy. This is not that. It isn't even a flat tax on companies as requires the company to have a large minimum amount of revenue.

Increased tax on large profitable companies in another form would also be fine.

The thing is, it wasn't taxing workers. It was taxing businesses. This was _not_ coming out of workers paychecks. Income tax is illegal per the WA state constitution.
