BD should emulate china. The model for success.But
S.korea sounds like a better role model for BD. 
If you ignorant self didn't know, Territorialy BD is bigger than countries like S.korea and Greece and we lost tons of land
during the battle of palashi. Some of those land are under your control.
Sir I do appreciate your thinking to see your nation among the country like South Korea one day but things aren’t that easy. things work in a certain way, regardless what we 'believe' in. South Korea is categorized with Japan, with in company of Taiwan/ Hong Kong also. Its a different region who faced revolution of industrialization in 60s when the country like India/ China was sleeping and their professional were moving to US/ UK/ West to work for their industries. Then we saw the similar things happening in ASEAN region since 70s which helped the country like Thailand, Singapore, Malaysia, Indonesia, Philippines going on the path of very high growth, in between 70s to 1997, the time when ASEAN dragged into deep recession. It is found that GDP per capita income of Thailand could reach its 1997 level by around 2006 as China had also adopted liberalization since 80s and took business of ASEAN region in between late 90s till now, which didn’t let the ASEAN region to gain the status like Japan/ South Korea, you are dreaming for Bangladesh. and then we have India also who came on this path of industrialization since 1990
And if we fit the country like Bangladesh, Pakistan then it is more wise to put them in the company of the country like Philippines which is of similar sized country and receive heavy remittances from West due to Christian religious background, around over $20bn every year, similarly how Pakistan and Bangladesh type similar size country receive over $10bn remittances every year. But if you check per capita income on PPP of ASEAN then we find them starting from Singapore at $60,000, Malaysia at $15,500, Thailand at $9,700, Philippines and Indonesia at around $4,000 each. Here it is worth mentioning that its only the technological advantage why we find Singapore in the company of Japan/ Korea while Malaysia little higher than Thailand as Malaysia is not only an energy independent small country but also it get good money through export of oil. Even Indonesia doesn’t have to import oil (very less).

From here, if you dream to become a country like Singapore/ Japan/ S.Korea then you gotto do what they did in their country, like how China is on that path and India is also somewhere behind/ close to China.
but on the path of Philippines, you may hardly double your per capita income by doubling remittance to $20bil like Philippines, also neither West is going to help you like how they helped Philippines to get it categorised among NICs with Thailand/ Malaysia

also, there is a population growth factor also, you have to deal with. With 0% population growth and 10% growth rate during last 21 years, Chinese per capita income on PPP is now 8 times to their 1990 level. And with 7% growth and around 1.3% average population growth, Indian per capita income on PPP could also be around 4 times to its 1990 level. This way Chinese per capita income on PPP is around 2.1 times to that of India right now, from almost the same level with India in 1990. But if we fit Bangladesh with expected 5% to 6% growth rate for next 40 years with around 2% population growth also, hence resulting 3% to 4% growth in per capita income, GDP per capita on PPP of Bangladesh by 2050 would be around 4 times to the current level of $1,700 means around $7,000 per head on PPP at 2011 price, which is still much less than the current level of Thailand in 2011. Similarly if we consider around 5% growth rate of Pakistan by next 40 years with 2.5% population growth, hence resulting only 2.5% growth rate in per capita income by next 40 years, per capita income of Pakistan would be around 3 times to the current level by 2050, means around $8,000 on PPP at the price of 2011.
And if you try to fit their growth with other Asian tigers like Thailand, India, China then we find, Thailand would at least have 4% growth rate on average for next 40 years with 0% population growth making its per capita income to be 4 times at around $40,000 on PPP by 2050 at the price of 2011. And if we consider India with 7% average growth rate with 1% population growth for next 20 years and then 0.5% by last 20 years, its per capita income would grow by around 6.25% for next 40 years adjusting population growth, which will double its per capita income by every 11.5 years, means around 10 times to the current level by 2050, means around $37,000 per head on PPP at the price of 2011. And as growth rate of China would slow down after 2020 due to aging population, its per capita income, from $8,300 in 2011, would be somewhere near Thailand by 2050, at around $40,000 on PPP at the price of 2011
Hence,
if you will depend on the remittances of Bangladesh only and try to even double to over $20bil/ year like Philipinnes, then you will be hardly somewhere around a similar size country like Philippines by 2050 which is also heavily dependent on the remittances. And,
this way with the expected growth rate less population growth, per capita income of Bangladesh, Pakistan, India, Thailand, China by 2050 would be around $7,000, $8,000, $37,000, $40,000, $40,000 respectively on PPP at the price of 2011 
. it is the case, when we don’t see any dramatic change in the world’s economic structure during next 40 years, as its highly likely that Western economies will have been fallen baldly sometimes in between 2015 to 2030 which may either help the emerging economies get inflow of foreign investments from West, or, it may slow down their growth due to an expected long recession period during the period of fall of US’s and EU’s economies
Just opposite we see when we compare relationship of India and China with West 
But it is also said in India, “Bujhate Diye Ki Dhadhak.” (it means, "when a candle is about to be off, it produce bit more light at that end time".) similar thing I can see nowdays when I find Western leaders talking bit high 
. Britain type countries are destined to be categorized with Pakistan, Nigeria, Thailand, Indonesia, Egypt size economies by 2020 to 2025, while their colonies like Australia/ Canada are already falling on the dominance of migrants. therefore, sooner they adopt habit to behave rightly while dealing world politics, better it will be for these current developed economies
