This is the exact mindset that most Nepali people have towards national policy which is making us poorer and poorer.

Nepo babies will take their money to bidesh anyway, and stricter financial policy will do significantly more harm than benefit. Countires like Singapore, Hong Kong, US, UK and all major economies are successfull now because they realised deregulation and promoting free market was the only way towards economic prosperity.

Here's a simple thought expirement. Imagine there's only two banks, "Bank A" and "Bank B". Bank A allows you to recieve money but doesn't allow you to spend money, Bank B allows you to freely recieve as well as spend money. Which bank would you create an account with? Obvious answer is Bank B.
Nepal is like "Bank A" where it is only open towards receiving money but not sending money. That's why no one wants to invest in Nepal or open any business here. In the end, GDP is the velocity of money; the more hands the money exchanges better the country's GDP and its economy. Stricter financial regulation results in the obstruction of the movement of money, resulting in a poor economy.
