I don't like to see my money being wasted on taxes. With Polish politicians there's zero chance that taxpayer money will be used reasonably.

Well, as a contractor I pay one third of the taxes I would pay as an employee, so much less waste.

You're still an employee, the only difference is whether you're "employed" by yourself or your.. actual employer.

Even if that was true... why should I care?

Backtaxes aren't fun, especially when they're caused by deliberate fraud.

That's my client's problem, not mine.
