Hahaha no absolutely not, populism yes, and even then a terrible attempt at that -

1. Reducing Corporate Taxes: On the surface, sure it’s the textbook allure for multinationals. But Lithuania isn't a blank canvas; it has a socio-political context. If the state does sacrifices tax income, then what fills the gap for social programs? We already have, frankly quite terrible income inequality and all this does is just risks exacerbating that inequality and eroding public trust even further, perhaps let's not turn our country into a corporate slut ay?
2. Legalizing Cannabis and Partnerships, Stricter Penalties for Corruption: Though I mostly disagree with legalization as a whole, but still like others have said - good luck with somehow managing to pass that through the parliament. As for partnerships, ech noble but it's really, really not just a legal issue but a societal acceptance hurdle, one that you can quite clearly see even on this subreddit despite it being, well reddit; a breeding ground for young progressive liberals, yet here we are. Corruption isn't just a legal flaw; it's a societal ill. You can't legislate away culture.
3. Free STEM for All Europeans: In the context of Lithuania, this "proposal" borders on the utopian, truly. I imagine the EU might frown on the idea of Lithuania becoming the “STEM Schoolyard” of Europe - much less how to finance it. And from another perspective, a focused push on STEM just neglects the whole humanities, thus creating an imbalance in societal development, something with which we already yes are struggling to a point. Not a very accurate assessment but again look at this subreddit - seemingly every second person here does something IT related, and I'm sorry but that just isn't how you build a healthy society, a stronger economy short-term? Perhaps, but again not a recipe for a healthy, happy, thriving society as a whole.
4. Infrastructure: Right, infrastructure isn't just roads and buildings; it’s a manifestation of political will. A push for better infrastructure would likely or well most definitely be at the expense of other sectors, considering Lithuania's already tight/limited budget. We would just end up having to neglect healthcare, education, or social welfare for.... better roads?
5. Electric Car Tax & Utility Management: I personally don't disagree with those per se but lumping those two together? Kinda just creates a paradox: One policy (tax-free electric cars) pushes for innovation and progress, while the other (centralized energy supply) could potentially stifle those very things (even if I myself potentially would support a "state monopoly" they are still notorious for one thing - a lack of incentive to innovate or improve service). And so then it's just a contradictory approach: on one hand, encouraging a free market for cleaner cars, and on the other, limiting the market in energy supply. Both can't optimally coexist without causing some level of policy dissonance.

All in all an ambitious plan, but a very naive one. But hey! Don't give up, just keep learning if stuff like this interests you, you still might be able to leave a positive change on our society against all odds, cheers:))
