To that effect, the pictures of modernism you see from the colonies are restricted to a few cities, and a few minority people from those cities. Bulk of the population masses lived in absolute poverty, illiteracy and there wasn't even a glimmer of hope for the future. The pictures misrepresent a non existent past, making it look like when natives were under colonisation, every last nook and corner of the country was overflowing with affluence, modernity and education. The reality is the exact opposite.
Since independence government spending is a lot more uniform and focused towards the benefits of Indians. Building infrastructure, institutions and projects that make sense towards national interests and not to make some European colonial power win WW1/2.
I wouldn't be surprised if that is the case with other former colonies of Europe.
