I'm going to dive deeper into this topic, because there are a number of inter-related issues that need to be highlighted. The data here comes from the 2016 Economic Census, cross referenced with the subsidiary report on SMEs from the same survey.
Before jumping into how an RM1,500 minimum wage might impact SMEs, let me digress into a discussion of the nature of the capital share of GDP.
The 2020 split on the share of GDP was 37.2% labour and 60.1% capital (the residual is taxes and subsidies). This of course has given rise to accusations of greedy capitalists, which is (a little) unfair. Yes, the capital share in Malaysia is high by developed country standards, but its not out of line with other emerging markets. More importantly, the capital share is not the same thing as the share of income going to the business owner/shareholders.
