Grass (the trimmed always green lawn type) is more demanding than many other crops. If the grass is growing there, then the topsoil is good enough for some other things too. Also the topsoil is something you can develop, especially on such small scale as personal garden. Make compost, grow less demanding plants first nad your soil will get better. You can grow things on sand mixed with a bit of compost.

But the same shit is often sold on European (like Polish Allegro) and American (Amazon) platforms. Why is this a problem only when then Chinese do it? The problem is broader, but is often shown us ‘do not buy from Temu or Aliexpress – they are dangerous’ while ignoring the same practices on the Western platforms.

The Western resellers most probably buy in bulk, so ‘de minimis’ rule does not fully explain why the dangerous product are on the market here.

I am all for making the platforms responsible, but why not start here, where enforcing this should be much easier? Or maybe it is not about safety and other regulations, but more about taking down competition?

the more educated people tend to vote either liberal or left

And this might be the reason. More educated, middle-class, from large cities are ‘the elites’, but not a significant majority. Poor, less educated people, from rural areas feel excluded in the world made by and for ‘the elites’. So they are going to vote against what the elites want. And, on top of that, the opportunistic rich ‘1%’, with means to influence politics, abuse those feelings for their own gain.
