Wow,

Great job here Pierre, with 2 postings !

I have comments and questions related to both postings..

But let us start with your first posting about HT Industry ..

As can be seen, dirty industry ('polluante') is heavily taxed, whereas high.tech ('de pointe') is very lightly taxed. Has anyone else played with tax rates, and has seen some effects?

I recall having similar success  in the past using this same tax reduction strategy for low HT Ind tax rates..
I would say it helped "some"...

But it still takes some effort to convert older dirty ind to HT or even to grow HT lots in the first place..

Okay so on your second posting-

My question is: is this still available in NAM 37?

Yes i think all the same older ramps have been made available for NAM 37 -
