Don't judge a plan by it's goals, but by its methods and results (foreseen and unforesoon).
Well, Morawiecki's plan includes a commitment to reduce the barriers to business and to make it much easier to start and operate a business. Fine, it's always a good idea to lower barriers. It's not even about taxation (Polish taxation isn't much of an issue, except the crippling social insurance contributions for businesses), but about the general business climate. He's made all the right noises - we should focus on tech, we should be more mobile and dynamic - all of this, I agree with.
But at the same time, PiS are busy giving extra powers to government agencies. For example - let's say we have a Polish entrepreneur who wishes to invest in a very large organic blueberry farm. He sees the price that they sell for in the West ($5 for 150g of organic blueberries) and spots the potential for export. Unfortunately, PiS have changed the law, so that he can't buy agricultural land if he doesn't live in the neighbourhood and isn't already a farmer. OK, so he approaches the biggest farmland owner - the agricultural property agency. They offer him a mere 5 year lease as the law also prohibits them from offering longer leases.
What does he do? He walks away.
Our entrepreneur then decides to open a factory producing a relatively obscure (but in demand) piece of IT equipment. He finds a suitable factory, makes a great deal, etc etc. He goes to the bank for funding, only to discover that commercial loan rates have gone through the roof because of the tax on assets held by the bank.
What does he do? He can't fund the factory entirely by himself, so he walks away.
Finally, he decides to open up a small clothing factory producing high end lingerie for the Western market using skilled Polish seamstresses. The initial investment isn't large, so he self-funds it. After 6 months, an employee demands a large payrise. He refuses and lets her go, but she decides to report him to PIP - the workplace/labour inspectorate. The law has been changed by PiS so that they are allowed to act as judge and jury, and they give him the maximum 30,000zł fine for various small breaches of the law.
What does he do? He sells up, takes his capital and opens in another country where the business environment is friendlier.
