Actually we are seeing some work in taxation, though not at the pace we'd like to see. So you can't say that "we are not seeing anything". Government introduced this withholding tax to bring people in the tax net. But you know what happened? The traders called for strikes. These traders are the most pampered community of Pakistan. They enjoy a tax free life while importing the cheapest Chinese junk they can find. Government has now halved the tax rate till September to give these guys time to file their returns. What can the government do when the biggest sector of your economy is not willing to play fair?
For energy, I am sure you have read a million times that these projects take time. Government made this mistake of going for expensive fuel again (LNG); the same mistake PPP made in 90s to go for oil based plants. But other than that coal fired plants, small hydro (in KP and Punjab), small to medium wind (in Sindh mostly) are coming along nicely. If everything goes well, we'll be out of this mess by 2017, insha Allah.
And Eid mubarik
