Earlier quoted context omitted.
Third world countries have already financed the draining of European swamps. It’s the wealth stolen in Asia, Africa and America that made those public works projects possible in the first place. The reason former colonies haven’t been able to do the same at home is because their society and economy are permanently crippled by colonization.
Not sure why you're being downvoted. Colonization, was brutal, self-serving, and its economic consequences are still felt to this day (especially when neocolonialism through private corporations and puppet governments is still a thing).

Here's an interesting passage from Early China: A Social and Cultural History ( https://www.amazon.com/dp/B00GA22L0E/ ):
> Even when we are talking only about the areas that can be considered as part of Early China, back in a time when "China" as a nation was still in her infancy, we find that more cultural developments had taken place in the valleys and strips of plains that are surrounded by mountains and plateaus on the second step mentioned above, or on the transitional belts along the major mountain ranges, but not at the centers of the floodplains located in the east. The reason for this development was simply ecological, given the fact that in the second millennium BC most of the eastern China plains were still covered by marshes and lakes[2], and the coastline in some sections was at least 150 km inland from today's seashores. The pre-Qin texts record the names of more than forty marshes or lakes on the North China Plain, most of which had dried out after the third century AD. In fact, for millennia the North China Plain was continuously caught in the process of sedimentation by the Yellow River which carried on its way east huge quantities of earth from the topographical second step [areas 1-2 km above sea level].
> [2] Even in the historical period, it was recorded that the Yellow River had changed its course some twenty-six times.
The Yellow River killed vast numbers of Chinese who farmed its banks, even being given the name "China's sorrow". But efforts were made:
> Over time, as the bottom of the channel gradually rose, the river overflowed its banks. Dikes were built ever higher to prevent flooding, and in some places the river started to flow above the surrounding countryside. Today, in a stretch of about 1,100 miles, the Yellow River moves along 11 yards above the plain.
> Under the Qin and Han empires [roughly 200 BC - 200 AD], the Yellow River was the core of Chinese civilization, home to around 90 percent of the population.

During that period, the Chinese hadn't really settled farther south, because... it was full of swamps. But the swamps were drained, the people moved in, and the Yangtze River basin and areas further south had become the demographic center of China by the end of the Tang dynasty in, um, 900 AD.
Tang China was probably the wealthiest country in the world at that time. But it was much poorer than any country today.
Warring States China in 400 BC was much poorer than that.
So no, no one has been "permanently crippled by colonization", and if they had, draining the local swamps would still be well within their means.
